This is really just a style issue, but you can use String instead
of java.lang.String. That might make you code a little shorter.
All classes in the java.lang package are imported automatically
and you can import new classes with the java::import command.

The JVM is using SIGUSER1 here to send signals between
threads. This is not a crash. You should set gdb to
ignore this signal and just deliver it to the application.
You can query the signals settings using the "info signals"
command in gdb.
You should be able to set gdb to send SIGUSR1 to the
program with the following command.
handle SIGHUP pass noprint nostop
Try that and see if you get a crash.
