Subject Re: Rather worrying exception with 5.2.4 (java.util.ConcurrentModificationException)
Date Fri, 04 Feb 2011 08:30:50 GMT
That is worrying, but I'd appreciate if you can get the more complete
stack track from the console. It looks like the failure was inside
page.attached() ... and that could be just about anything.  It is
likely a 3rd party library that is not fully compatible with 5.2.4,
and it would be good for everyone to figure out which one.
