Ian Springer updated JBVFS-108:
-------------------------------
Attachment: JBVFS-108.patch
Here's a patch that should fix this in 99% of cases by iterating over a copy of the tempInfos Map instead of the original. A CME is still possible, though much less likely, if another thread modifies the original Map in the middle of the iteration needed to make the copy.
