I'm not sure, but there's a decent chance that 
the plain Debug still uses the same debug port as 
the "real" parser.  Most likely it's sharing 
classes for simplicity.

Try using -bv as well -- that will tell you which 
process is listening on that port.  Most likely 
you've got a dangling copy of the parser lurking around somewhere.
