Crash Hotspot

Mon Jan 25 13:14:27 UTC 2010

I've experienced a number of hotspot crashes with b78 - b80.  They seem to
appear only when I enable the use of the G1 GC.  I've attached a number of
crash logs.  I'm running NetBeans 6.8 (which crashes once in a couple of
hours) with the following options:

netbeans_default_options="-J-Xss2m --fontsize 12
-J-Djava.library.path=/usr/lib64/ -J-Dapple.laf.useScreenMenuBar=true --laf
javax.swing.plaf.metal.MetalLookAndFeel -J-XX:PermSize=32m
-J-XX:MaxPermSize=100m -J-Xmx1024m -J-Dnetbeans.logger.console=true
-J-XX:+DoEscapeAnalysis -J-XX:+UseCompressedOops
-J-XX:+UnlockExperimentalVMOptions -J-XX:+PrintGCDetails -J-XX:+UseG1GC"

When I instead use the default GC with the other command line parameters
unchanged then everything runs smoothly for days.  If I can provide any more
info regarding my setup, do let me know.

BTW, I was wondering if there is another way I should report errors?  I've
had a look on the openjdk page on the subject (
http://openjdk.java.net/guide/bugDatabase.html) but that was not up-to-date.

Kind regards,

Mark
