Description David Williams

2011-09-19 22:54:22 EDT

I've seen a few "concurrent modification exceptions" lately. Just thought I'd report. The only think I was doing was opening the b3 aggregator editor, on Juno's "simrel.b3aggr" file. The version I have installed is from 8/16.

I do see, now, there is an 8/18 version ... maybe this has been fixed already? ... so, I installed that 8/18 version.

I see I've opened this bug several times. Even though this is the older bug, will mark as dup of new bug.

[Bookkeeping change only. Moving bugs to the new "home" of aggregator, CBI.
Made no changes to assignee's for closed bugs, even though some were old inbox.]
