Description mildegeister 2017-10-18 15:41:51 UTC

Product Version = NetBeans IDE 8.2 (Build 201609300101)
Operating System = Mac OS X version 10.12.6 running on x86_64
Java; VM; Vendor = 9.0.1
Runtime = Java HotSpot(TM) 64-Bit Server VM 9.0.1+11

Reproducibility: Happens every time

STEPS:
initial:
  * close NB where some open files are visible in tabs - individual implementations as well as JavaFX classes
  * install JDK9 (over JDK8)
reproduce:
  * restart NB

ACTUAL:
  * NB is starting with an pop up about missing target server (which maybe an old issue) and project background scanning starts but stops again very quick.
  * some of the tabs are recovered (e.g. TableView.java and some of my own implementations), others are not (e.g. TableViewSkin + TableViewSkinBase and some others of my own implementations)
  * "TableViewSkin - Navigator" is written on left hand side (Project Browser?), but entire area is grey with "<No View Available>"
  * From Tools menu no entries are accessible, except "NetBeans Plattforms", so I cannot even manually redirect to the new Java Platform
  * on lower right/footer there is one red Icon with "You have 1 unread notification" on mouse over, its about this Unexpected Exception, but it cannot be opened/read. On double click an empty Notification window is opened.

EXPECTED:
  all projects explorer is visible, old state of expanded notes is restored
  all file tabs are restored
  Tools menu is fully accessible

NetBeans 8.2 does not work with JDK 9. For more information, please see https://jaxenter.com/netbeans/using-apache-netbeans-incubating-jdk-9

Comment 3 mildegeister 2017-10-19 11:18:03 UTC

Quick solution:

Temporary shell based script:
- on the console check which versions exist on your machine:
JAVA_HOME -V
- put this line in starting script of NetBeans:
export JAVA_HOME=`/usr/libexec/java_home -v 1.8`
(assuming that any major version 1.8 exist)

Permanent change to the OS:
- go to: /Library/Java/JavaVirtualMachines/jdk-9.0.1.jdk/Contents
- rename Info.plist --> Info.plist.disabled
- restart NetBeans, it will pick the next highest (valid) JDK available
