Why is this bug set on WONTFIX? 
This is one of the frequent issues I encounter. It seems to have a lot of duplicates:
http://statistics.netbeans.org/analytics/detail.do?id=202589
Is this due to a JDK bug? 

Thank you

Just switch to JDK 7 and you should be fine.

I was participating in the Netcat, about to open a class with the same name as one I just closed (but in a different package).

Sure because it's a JDK bug which is fixed in dev builds of JDK 9 only.

Is netbeans (being part of oracle) asking the JDK team to backport the JDK 9 fix to JDK 8?

And there must be workaround. Perhaps with a different implementation of the affected code. This bug comes very often and gives a very bad UX.

The LinkedList is in DefaultKeyboardFocusManager which is an AWT class so there's no workaround.

Comment 16 _ gtzabari 2014-03-05 15:57:41 UTC

I'll repeat the question: did anyone ask Oracle to backport the fix to JDK8?
