1, run netbeans in debug mode inside netbeans 2, Open options and change laf to Dark Nimbus 3, Netbeans give you option to restart - restart netbeans 4, restart failed and this is in output: FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197) ERROR: transport error 202: connect failed: Connection refused ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510) JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [../../../src/share/back/debugInit.c:741] /home/mito/nb/jet-main/nbbuild/netbeans/platform/lib/nbexec: line 450: 3362 Aborted "/usr/lib/jvm/java-7-sun/bin/java" -Djdk.home="/usr/lib/jvm/java-7-sun" -classpath "/home/mito/nb/jet-main/nbbuild/netbeans/platform/lib/boot.jar:/home/mito/nb/jet-main/nbbuild/netbeans/platform/lib/org-openide-modules.jar:/home/mito/nb/jet-main/nbbuild/netbeans/platform/lib/org-openide-util.jar:/home/mito/nb/jet-main/nbbuild/netbeans/platform/lib/org-openide-util-lookup.jar:/usr/lib/jvm/java-7-sun/lib/dt.jar:/usr/lib/jvm/java-7-sun/lib/tools.jar" -Dnetbeans.default_userdir_root="/home/mito/.netbeans" -Dnetbeans.running.environment=gnome -Dnetbeans.dirs="/home/mito/nb/jet-main/nbbuild/netbeans/nb:/home/mito/nb/jet-main/nbbuild/netbeans/ergonomics:/home/mito/nb/jet-main/nbbuild/netbeans/ide:/home/mito/nb/jet-main/nbbuild/netbeans/extide:/home/mito/nb/jet-main/nbbuild/netbeans/java:/home/mito/nb/jet-main/nbbuild/netbeans/apisupport:/home/mito/nb/jet-main/nbbuild/netbeans/webcommon:/home/mito/nb/jet-main/nbbuild/netbeans/websvccommon:/home/mito/nb/jet-main/nbbuild/netbeans/enterprise:/home/mito/nb/jet-main/nbbuild/netbeans/mobility:/home/mito/nb/jet-main/nbbuild/netbeans/profiler:/home/mito/nb/jet-main/nbbuild/netbeans/python:/home/mito/nb/jet-main/nbbuild/netbeans/php:/home/mito/nb/jet-main/nbbuild/netbeans/identity:/home/mito/nb/jet-main/nbbuild/netbeans/harness:/home/mito/nb/jet-main/nbbuild/netbeans/cnd:/home/mito/nb/jet-main/nbbuild/netbeans/dlight:/home/mito/nb/jet-main/nbbuild/netbeans/groovy:/home/mito/nb/jet-main/nbbuild/netbeans/extra:/home/mito/nb/jet-main/nbbuild/netbeans/javacard:/home/mito/nb/jet-main/nbbuild/netbeans/javafx:" -Dnetbeans.home="/home/mito/nb/jet-main/nbbuild/netbeans/platform" '-Dnetbeans.importclass=org.netbeans.upgrade.AutoUpgrade' '-Dnetbeans.accept_license_class=org.netbeans.license.AcceptLicense' '-XX:MaxPermSize=384m' '-Xmx768m' '-client' '-Xss2m' '-Xms32m' '-XX:PermSize=32m' '-Dnetbeans.logger.console=true' '-ea' '-Dapple.laf.useScreenMenuBar=true' '-Dapple.awt.graphics.UseQuartz=true' '-Dsun.java2d.noddraw=true' '-Dsun.java2d.dpiaware=true' '-Dsun.zip.disableMemoryMapping=true' '-Dplugin.manager.check.updates=false' '-Dnetbeans.extbrowser.manual_chrome_plugin_install=yes' '-Dnetbeans.full.hack=true' '-Xdebug' '-Xrunjdwp:transport=dt_socket,suspend=y,server=n,address=localhost:34030' -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath="/home/mito/nb/jet-main/nbbuild/testuserdir/var/log/heapdump.hprof" -splash:"/home/mito/nb/jet-main/nbbuild/testuserdir/var/cache/splash.png" org.netbeans.Main --cachedir "/home/mito/nb/jet-main/nbbuild/testuserdir/var/cache" --userdir "/home/mito/nb/jet-main/nbbuild/testuserdir" "--branding" "nb" 0<&0 /home/mito/nb/jet-main/nbbuild/templates/projectized.xml:402: The following error occurred while executing this line: /home/mito/nb/jet-main/nbbuild/build.xml:925: The following error occurred while executing this line: /home/mito/nb/jet-main/nbbuild/build.xml:1000: exec returned: 134 BUILD FAILED (total time: 15 minutes 35 seconds)
Reproduced. NetBeans are run with the debug options after restart, but debugger has finished on NetBeans exit. Debugger has no way to detect, that the application (NetBeans) is going to be run again. IMHO the best fix for 7.4 is to remove debug options on restart. In the future, we may add some interface, that would allow to notify debugger about the restart.
I do not consider this to be severe enough to make changes into the launcher just few days before code-freeze. In the future we may want to introduce some mechanism that would allow the debugger to detect, that the application is restarting. On UNIX systems this issue can be solved by applying the attached patch to netbeans/platform/lib/nbexec.
