I think you should do more error checking here. If you look at ClhsdbLauncher
you will see:
// This will detect most SA failures, including during the attach.
oa.shouldNotMatch("^sun.jvm.hotspot.debugger.DebuggerException:.*$");
// This will detect unexpected exceptions, like NPEs and asserts, that
are caught
// by sun.jvm.hotspot.CommandProcessor.
oa.shouldNotMatch("^Error: .*$");
I think you could use something similar here.
