Subject: Can't debug with JRuby?!?!?

Greetings,

Well, after several years of hoping I finally landed a job that is at
least 50% Ruby development, woo hoo :)  Now then, we're also doing a
good bit of JRuby development and I've run into a snag which googling
and searching this group has failed to resolve: I can't debug from
JRuby! I've got to believe I'm doing something wrong that's so obvious
I'm missing it.  On JRuby 0.9.8 and 1.0.1, when I try to debug  I get
the following (see below) and I can't list the code, set break points
or anything else other than "continue."  Straight ruby has no problem
and debugs as usual.  I suspect the Signal.trap warning indicates that
what the debugger needs to do is not yet supported but I find it hard
to believe JRuby has gotten as far as it has w/the inability to debug
with it.  Anyone know what's up?

Best,

Ken
