Note: NetBeans Web and Java EE support are particularly demanding on system resources - especially when used in combination with application servers. While the above system requirements apply to most configurations of the IDE, for the best results make sure that your system meets at least the recommended system requirements when developing Web and Java EE applications.

Required Software

NetBeans IDE runs on the Java SE Development Kit (JDK) which consists of the Java Runtime Environment and developer tools for compiling, debugging, and running applications written in the Java language.

The tested JDK for this release is JDK 8u101 for Windows, Linux, and OS X. The 8.2 version of the IDE cannot be installed or run on the JDK older than JDK 8.

Note:

  • The PHP and C/C++ NetBeans bundles only require the Java Runtime Environment (JRE) 8 to be installed and run.
  • Java features in the IDE and JavaFX 8 features require JDK 8.

You can download the JDK for your platform from the Java SE Downloads page.

Note: Java SE 8 is required to install and run NetBeans IDE 8.2.

JavaFX Support

The JavaFX SDK is not bundled with the NetBeans IDE 8.2 release.

The JavaFX 8 SDK is bundled with JDK 8 for Windows, OS X and Linux. You can install the JavaFX 8 SDK together with Java SE Development Kit 8 as a co-bundled product.

Unlike previous versions of NetBeans IDE, NetBeans IDE 8.2 does not require that you set up an "FX-enabled" Java platform in order to utilize JavaFX support in the IDE. You can develop JavaFX projects in the IDE if you install JDK 8.

Please note that the supported JDK version for JavaFX 8 is Java SE 8.

See the JavaFX Release Documents page for more information about system requirements, supported platforms and known issues for the current and previous versions of JavaFX SDK.

Compatibility with Earlier Releases

When the IDE is run for the first time after installation you have the option to import some of the settings used in a previous installation. The IDE opens using the default settings if you choose not to import the settings from the existing installation. Note the IDE only recognizes previous installations when the user directory resides in the default location. It does not recognize installations that use the --userdir switch to specify a user directory. If you would like to import settings from a location that the installer does not recognize do the following:

  1. Start the IDE go to Tools > Options in the main menu.
  2. Click the Import button at the bottom of the Options dialog.
  3. In the Select Options to Import dialog, click the Browse button and navigate to the user directory that contains the settings you want to import. For more about the location of the NetBeans IDE userdir, see the FAQ What is a userdir and where can I find it?

Known Issues

Installer

The unresolved installer issues for this release are as follows:

  • Issue #93568: On Linux, installation hangs when the network connection is lost.

    Description: On Linux platforms, if the network connection is lost, installation hangs when the installer is searching for a compatible JDK in network directories.

    Workaround: Restore the network connection and proceed with the installation.

  • Issue #117172: A blank window when running the installer on Ubuntu.

    Description: The installer appears as the blank/gray dialog when running on Ubuntu with Beryl/Compiz/Compiz Fusion installed.

Core IDE

The unresolved Core IDE issues for this release are as follows:

  • Characters do not display properly in some Asian locales.

    Description: When running the IDE with some Asian locales on Ubuntu and some other Linux distributions, the IDE's screen text may become unreadable. On certain Linux distributions multi-byte characters may display as a rectangle due to JDK font setting issues.

    Workaround: Please see the FAQ for help with resolving this issue: http://wiki.netbeans.org/FaqI18nLinuxAsianFonts

  • Profiling application performance can fail when using the Advanced option.

    Description: The IDE displays the message "Redefinition failed with error 62" when attempting to profile application performance (CPU) and the Advanced (instrumented) option is selected.

    Workaround: Restart the application with the VM argument -Xverify:none to disable classfile verification. You must restart the application to disable classfile verification. You cannot disable verification if the application is running.

  • Issue #119617: Cursor lost in editor and cannot type using keyboard.

    Description: It can sometimes occur that after using a hint in the editor window that the insertion point in the editor disappears and you cannot type using the keyboard. This has mostly been reported on Mac OS X 10.4, but there have been some reports on some versions of Ubuntu.

    Workaround: Use the mouse to open and then close a dialog window (for example, a properties dialog). This returns the focus to the editor and the insertion point and keyboard will work as normal.

  • Issue #130357: I18N - OS X will not generate javadoc if the project name or path has multibyte characters.

    Description: The javadoc task is written in MacRoman, the default OS X encoding, when creating the temporary parameter file. This may be due to the BSD and Mach parts (system & kernel calls) accepting parameters in UTF-8, but the OS X and HFS only accepting MacRoman.

    Workaround: Avoid using multibyte characters in the name of the project or the path to the project.

  • Issue #207060: On Windows XP, UNC paths cannot be used as URIs.

    Description: On Windows XP, the automatic update of any file view (Project, Files, etc.) does not work when UNC style paths are used (for example, \\MyServer\myShare\myDirectory) instead of drive letters (for example, Y:\myDirectory).

    Workaround: Restart the IDE. Alternatively, choose Tools > Options > Miscellaneous > Files from the main menu, deselect the Enable auto-scanning of sources option, and select Refresh Folder in the context menu of a folder.

  • Issue #211406: Views and Palettes keeps scrolling itself to the drag position after drag-and-drop.

    Description: After dragging and dropping something from Projects or Files Views or Palette in GUI designers, when you scroll the View or Palette up or down it will scroll back to the drag position, requiring you to scroll to select some nodes and components.

    Workaround: You must restart the IDE.

  • Issue #231807: File chooser displays no file contents in the Open Project and Select Project Location dialog boxes.

    Description: On OS X, the file chooser is blank after File > Open Project is selected in the IDE or a folder for a new project location is selected in a new project wizard.

    Workaround: Disable the "Maximize Native Look and Feel" option.

  • Issue #256211: Test execution fails with Surefire 2.19.

    Description: When using Surefire 2.19, test execution is not performed and an error is shown that no tests are executed when running "test file" from the NetBeans IDE due to issue SUREFIRE-1191.

    Workaround: Use Surefire 2.18.

  • Issue #219756: On Linux, the ClassCastException is thrown when running the IDE on JDK 8.

    Description: On Linux, the ClassCastException is thrown when running the IDE on JDK 8 and the IDE's window becomes unresponsive after the machine wakes up from the Sleep mode. See JDK-7172749 for details.

    Workaround: Start the NetBeans IDE with the -Dsun.java2d.xrender=false parameter.

Web and Java EE

The unresolved Web and Java EE issue for this release is as follows:

  • Issue #183614: Step Into does not work properly with EJB.

    Description: When debugging a servlet, Step Into an EJB call stops at unrelated code.

    Workaround: Set a breakpoint in the EJB implementation code and use Step Over.

  • Issue #246431: Cannot run Java Web application on Linux on WildFly.

    Description: Web application fails to run on WildFly server on Linux due to encrypted partition.

    Workaround: Right-click the WildFly server node in the Services window and select Edit Configuration. Add the <journal-type>NIO</journal-type> element directly below <hornetq-server> and restart the server.

HTML5

The unresolved HTML5 issue for this release is as follows:

  • Issue #236967: Cordova projects may fail to build with Cordova 3.1.0.

    Description: Due to a Cordova issue the IDE might replace the old version of a plugin with a newer one, which can result in dependent plugins being removed and the Cordova project failing to build.

    Workaround: Perform the following steps:

    1. Remove core from the Cordova plugin name in the plugin properties file ([projectFolder]/nbproject/plugins.properties)
      (for example, changing org.apache.cordova.core.camera to org.apache.cordova.camera.)
    2. Delete contents of the [projectFolder]/platforms and [projectFolder]/plugins folders.
    3. Rebuild the project.

C/C++

NetBeans C/C++ support C, C++, Fortran and various Assemblers (x86, SPARC, etc.) applications on Microsoft Windows, Macintosh OS X, and Linux. C/C++ developers can bring existing applications into the NetBeans project system, or develop new applications and libraries. NetBeans C/C++ support covers the end-to-end development cycle: projects and templates, an advanced language-aware editor, makefile-based builds, and debugging.

The unresolved C/C++ issues for this release are as follows:

  • Issue #200196: On some Linux platforms, "Step Over" sometimes behaves as "Continue".

    Description: On some Linux platforms (Ubuntu, Debian, etc.), "Step Over" sometimes behaves as "Continue" when versions of GDB are equal to 7.2 or lie within the range of 7.2 to 8.0.

    Workaround: Use GDB versions earlier than 7.2, or GDB 7.4 and more recent, or specify "Console Type" (Project Properties > Run) to another option in the Terminal window.

  • Issue #225920: On Linux, C makefile build fails with the "Permission denied" error, if the tmp directory has no execution permission.

    Description: On Linux, C makefile build fails with the "Permission denied" error, if the tmp directory has no execution permission.

    Workaround: Set the execution permission to the tmp directory or run the IDE with the -J-Djava.io.tmpdir=<path_to_new_tmp_dir> option to redefine the tmp directory.

  • Issue #234221: On Windows 32-bit, the IDE (and 32-bit version of JDK) does not work with the 64-bit version of Cygwin and vice versa.

    Description: On the 32-bit version of Windows, the IDE (and 32-bit version of JDK) does not work with the 64-bit version of Cygwin and vice versa

    Workaround: Install and use the IDE, JDK, and Cygwin with the matching bitness (for example, all the three software components need to be 32-bit).

  • Issue #235406: On Windows, the IDE displays the contents of the Terminal window with low contrast.

    Description: On Windows, the IDE displays the contents of the Terminal window with low contrast.

    Workaround: Set the PS1 environment variable in the Cygwin <home_dir>/.bashrc file to another value.
