Comment 3 Miloslav Metelka 2012-05-30 12:37:17 UTC 
Only evaluating report 578467 (build 120501).
The TextLayout creation is expensive and there's no way how to overcome that.
There is JavaTokenId$1.embedding() related classloading but the only chance to eliminate this is IMHO a more thorough warm-up (reassigning to java for final decision whether to do it or not).
Comment 4 Dusan Balek 2012-05-30 14:30:13 UTC 
As can be seen from the attached snapshots, JavaTokenId$1.embedding() is blocked inside class loading which seems to be slow due to heavy IO load caused by some Maven project opening and running svn.
