jdb/java inconsistency

[parautenbach]

Hallo NG,

Pardon me if this problem has already been addressed on this NG, but I
couldn't find anything of any help, since I'm not certain what to
search for.

I'm making changes to a multi-threaded server daemon not written by
myself. This server interfaces with another server through WSDL-created
stubs. When I run the daemon it throws a number of exceptions, but not
when I run it through the jdb debugger. I use the exact call, just with
java replaced by jdb. All source code is compiled with the debug flag
on for both cases. This makes it really hard for me to debug. I suspect
that it might be a thread problem, although I have no definite grounds
for my suspicion. Has anyone ever come across something of this kind?
Can someone tell me the the fundamental differences between java and
jdb?

Any help will be greatly appreciated.

Regards
Pieter Rautenbach

This is likely not a "difference" between jdb and java, but some kind of
timing issue in your program. Since the debugger slows things down, the
timing can be different. One possible cause is threading.

To debug, you'll have to resort to using log statements.

Thanks Ray, I'll look into it that way.
