stacktrace
Actually this issue not reproducible for me but anyway the static set should be synchronized. Created attachment 79959 [details]
Proposed fix
If you always access it using 'synchronized (all)' then using Collections.synchronizedSet is superfluous. (Generally I find Collections.synchronized* not very useful because you so often want to do more than one operation at a time to the collection.) I will remove Collections.synchronizedSet from the patch. Fixed in the core-main Integrated into 'main-golden', will be available in build *200904151401* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main-golden/rev/2b1d0560aa74 User: Andrey Yamkovoy <kaktus@netbeans.org> Log: Fix for issue #162415 - java.util.ConcurrentModificationException at org.openide.util.WeakSet$WeakSetIterator.checkModcount |
