Comment 1 Alexander Simon 2008-08-27 12:33:38 UTC 
I cannot reproduce bug.
I have a guess: such thread dump can be if user debugs IDE. Is it right?
vv159170: Could you run unit test 
main/cnd.repository/test/unit/src/org/netbeans/modules/cnd/repository/disk/MemoryCacheTest.java?
Test simulates access to MemoryCache from 5 threads.
Unit test and some MemoryCache optimization are in the change set:
