Hi,

I'm glad to see I'm not the only one banging against bug 6588239 - did you find a solution to this?

Author

mpilquist commented Aug 3, 2011

Hello,

I haven't seen the problem in recent JVMs. Not sure if it was fixed by some other change or if it is still lurking. For a while, every faster machine I tried resulted in this bug occurring more frequently but I haven't seen the issue for about a year at this point.

Good luck!

arikkfir commented Aug 3, 2011

Unfortunately I'm seeing this on 6u26 so perhaps the fix was somehow reverted.

I just saw it again on 6u26... frustrating!
