Summary: ConcurrentModificationException upon loading nodes

Initial Comment:
Hi

I'm getting the cited exception not each time, but pretty 
often upon loading nodes from weblogic 6.1sp6 and 
8.1sp2. Some times it will continue upon pushing OK-
button, other times it will hang.

Maybe there should have been synchronised List here.

have a nice day
ThorÅge
