When you say "crashes the system" do you mean the JVM crashes or you 
just get the stack trace
you included in your message?

I don't think this is necessarily an IDV issue. Doing a google search:

I see somehow else had this problem on a Mac. Are you developing on the 
Mac? Does this also show up on other platforms?
