Hello,

I get about 20 error dialog boxes and the following is what I see in
the log file after.  It seems like it is triggered by viewing or
editting the ant build script from Eclipse Ant Editor.  But exact
sequence of actions that triggers this error is not consistent.  Any
ideas?  It almost looks like it's going going through a stack overflow.
