I put some fixmes on your code :9
I don't see the command really working well.
The problem with the shutdown is that it doesn't really shutdown the db, it
leaves it running (on linux at least) and the net result is that sometimes
the properties file says it wasn't shut down properly and then it fails. It
fails because for some reason the thread never really moves forward and
reach "HSQL 1.4 started". If it does then everything is fine. Go figure.
So what hangs the DB is the following sequence
1- unclean shutdown of hsql
2- restart
3- start of hsql takes time
3'- if 3 is finished before 4 then everything else is ok if not then...
4- JMX boot proceeds
5- hsql never really recovers or prints the "hsql 1.4 started"
6- JBoss is hung in boot somehow
Right now if you remove step 1 or 3' is true, it works, it seems the
shutdown procedure you coded in there is not foolproof.
One thing that would really be nice would be to build a callback in the boot
sequence of hsql so that the mbean would be notified and would wait until
exiting the "preRegister" right now I put a "wait()" that works but it is
not the best solution. If you do that then you can probably code a
hardcoded shutdown, something outside the JDBC call, go native?
