>> Are bugs #7068051 and #7077439 fixed in the current trunk ? > They are not fixed in OpenJDK for Mac OS X. Both bugs are fixed in HotSpot hs21-b18, but current trunk <http://hg.openjdk.java.net/macosx-port/macosx-port/hotspot> uses HotSpot hs21-b17. Thanks Tomas HotSpot hs21-b18 should be merged soon in OpenJDK for OS/X ?
