Hm that's unfortunate. Could you provide some reproducer for the problem?
Without the reproducer I can only suggest to experiment with jvm options to
narrow down the problem (or find a workaround). So...

1. Looking here: http://bugs.java.com/view_bug.do?bug_id=6896647
Try adding following line to tomcat/bin/setenv.sh:
JAVA_OPTS="$JAVA_OPTS -XX:-ReduceInitialCardMarks"

2. If 1 will not help, try setting different GC. If I understand the stack
trace correctly and my google-fu is good, the failure happens in PS Scavenge
for new generation. Here is my favourite table to choose GC for both old and
So I would suggest to try either "-XX:+UseG1GC" or "-XX:+UseConcMarkSweepGC
-XX:+UseParNewGC". They behave differently depending on your heap size, so if
both of them will work correctly try measuring performance for them.

3. And the last thing to try would be this:
Unfortunately case was left unresolved, but there are plenty of suggested

And please report the results, maybe that will give enough info for someone to
take a closer look...
