Causing an exception rather than calling the debugger

Hi, I embedded ABCL in an app some years ago. When an error occurred, ABCL threw an exception. It did what I want. Today I upgraded to the latest jar and I am experiencing a different behavior. When an error occurs ABCL enters a debug REP loop. Calling a REP loop on error is perfect for interactive use but not workable in an embedded situation. I'm hoping there is a simple way for me to change this behavior. Any help is greatly appreciated. Thanks. Blake McBride
