Yep, I think that is probably a likely workaround as well. For now I'm
recommending downgrade to our clients, rather than introducing cryptic XX
flags :)
lots of bugreps come in once you search for ReduceInitialCardMarks
Looks like a feature has been turned on :
http://bugs.sun.com/view_bug.do?bug_id=6889757
and now it is in wide-beta-test
http://bugs.sun.com/view_bug.do?bug_id=6888898
http://permalink.gmane.org/gmane.comp.lang.scala/19228
Looks like the root cause is a new Garbage Collector, one that is still
settling down. The ReduceInitialCardMarks flag is tuning the GC, but it
is the GC itself that is possibly playing up, or it is a old GC + some
new features. Either way: trouble.
