Thread dump

Happens every time I run java.j2seproject tests. The tests deadlock with following thread dump.
Comment 1 Jaroslav Tulach 2012-06-04 12:43:59 UTC 
org.openide.util.lookup.ProxyLookup$LazyCollection.computeDelegate(ProxyLookup.java:1106) calls org.openide.util.lookup.ProxyLookup$LazyCollection.toArray(ProxyLookup.java:1143)
under a lock and it probably should not.
Comment 2 Jaroslav Tulach 2012-06-07 07:22:20 UTC 
I have improved the above problem in 6bc80035a076, but the test still deadlocks.
