Comment 1 Martin Kozeny 2013-07-19 14:24:17 UTC 
According to first snapshot: probably awt is waiting on read mutex in Opening Projects thread with writeAccess mutex - there is invoked method findBinaryNBMFiles() so many times (259x) and inside method isFile() almost 400 times...Rest ones are similar but awt is waiting for writeAccess...
