Description _ tboudreau 2007-06-06 05:14:00 UTC 
Saw this while I was on an airplane several times while typing (I don't think
the airplane has anything to do with it, but I couldn't tell you now what
exactly I was doing).  It seemed to happen when a java reparse was happening, so
I'd guess the data the error stripe was displaying was out of date.  

Given that it happens inside a TreeMap, the likely cause is one thread modifying
the map while the event thread is iterating it.

Looks like slightly different reincarnation of the same synchronization problem.
