The JDB is called to run the very simple application
(see java source below).
Then the "stop in regresab45.main" and "run" JDB commands
are given. After breakpoint the "cont" JDB command is
given and JDB is expected to finish.

But the further behaviour of the JDB is not correct -
one more breakpoint happens.
After this on Solaris the application hangs.
On Win32 the application does not hang and the
next "cont" JDB command after the second unexpected
breakpoint completes the application and JDB.

These failures happen with the following HotSpot VMs:
Java HotSpot Client VM (build 1.3.0rc2-Y) on Solaris;
Java HotSpot Server VM (build 2.0rc2-D) on Win32;
Java HotSpot Client VM (build 1.3.0rc2-Y) on Win32;


This bug prevents the regression test (testbase_nsk)
nsk/regression/regresab45 to pass.

Under the Classic VM the JDB runs well.
The HotSpot Client VM (build 1.3.0rc1-T) on Win32 is OK too.
