1) null pointers

(I posted a bunch of questions to the IDE newsgroup without getting an
answer.  This one is debugger related)

I have JBuilder 2.  We also use the Visigenic ORB (separate product), and it
throws a ton of handled null pointer exceptions. This is a real pain in
debugging. Is there some way to ignore breakpointing on exceptions based on
something or other that is unique to the ORB? Like the package or something?

My goal is to catch handled null pointers as they occur.  When *I* have a
bug in my code that has a null pointer, then I want to catch it.  But, we
catch everything, so I can't breakpoint on unhandled null pointers.

2) Huh?

When I startup a largerish program, I get:

Exception breakpoint  occurred at line 265 in file
[D:\JBuilder2\java\src.zip]\java\lang\ClassLoader.java. :
java.lang.ClassNotFoundException thrown (unhandled). Do you want to continue
running?

... that appears in the Execution Log.  But, it never lets me answer the
question.  It just continues.  That is OK, but I would like to know what's
going on.  I get three of these, and I only know why one is there.  Also,
how can I figure out the class?
