Re: Debugging with JDEE

I recommend using jdb. I haven't used jdebug in a while. But the last
time I used it, stepping through the code was slower than with
jdb. The speed difference is considerable. Obtaining the values from
variables from step to step was a bit troublesome. The most annoying
part was the debugger getting out of synch. This used to lead to
jdebug getting hung. This behavior did not happen consistently it will
work correctly for most of the debugging session until you get to the
part you were interested in. Then debugger will get stuck and you have
to start all over again. I was never able to figure out what triggered
the condition.

The only feature jdb does not have which I wish it did is conditional
breakpoints. jdebug supports this feature to some extent. For
everything else I find jdb sufficient.

For large projects the easier way to get either debugger working is to
start your application using the flags -Xdebug
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,addresss=4444
and then attach using either debugger.

For a simple test case just running the class within the debugger is
enough.

There are other integrations to debuggers like JSwat. I haven't used
them but I think they only start the debugger from emacs.
