Description Vladimir Riha 2013-10-01 13:55:07 UTC

Participant.dump

Please let me know if Participant.dump helps you reproduce this issue.
Comment 5 _ gtzabari 2013-10-08 04:11:05 UTC 
Increasing priority as this issue occurs very frequently with no known workaround.
Comment 6 _ gtzabari 2013-10-08 04:12:21 UTC 
Also, I am fairly certain that this regression was introduced over the past 2 weeks. Older dev builds didn't have this problem.

Writing code.
Comment 10 _ gtzabari 2013-10-10 22:08:31 UTC 
I stopped submitting reports for this issue using the exception reporter because it occurs too frequently (once every 10 seconds using build 201310050001). Increasing to P1 :)

In the meantime, I'm going to try upgrading to a newer version.
Comment 11 _ gtzabari 2013-10-10 22:25:50 UTC 
FYI, I am able to reproduce this with today's build (201310070001) as well.
Comment 12 David Strupl 2013-10-11 05:21:56 UTC 
Guys, is this present in 7.4? I hope not! Please speak up. If not I will update the version field .. Thanks for quick info.
Comment 13 Vladimir Riha 2013-10-11 05:51:27 UTC 
I haven't seen it in 7.4 even with assertions enabled but I don't have exact steps to reproduce...
Comment 14 David Strupl 2013-10-11 07:17:55 UTC 
Ok, let's treat it as not present in 7.4. If it turns not to be the case let's change the Version and Keywords back.
Comment 15 Dusan Balek 2013-10-11 13:31:17 UTC 
Finally able to reproduce it. Fixed in jet-main.
