JDEbug uses Sun's Java Platform Debug Architecture. The engineering manager
for JPDA informs me that JPDA does not work reliably in HotSpot mode. The
JPDA team is working on a solution to this problem.

Please submit a bug report so that I can figure out the exact nature of the
problem you are experiencing.

Remember that JPDA and JDK1.3 are bleeding edge technologies, especially on
Solaris and Linux. Problems are to be expected. Please be patient.
