There is no such thing as a crashed java thread. It either terminated
or is still running. You are supposed to explictly close your
connections to the db in java. If you don't you will have to wait until
the Connection object is garbage collected for it to be closed. If your
java app is sitting around not doing much then it might never get around
to calling the garbage collector.
Bottom line:
1) expliclty close connections yourself
2) Call System.gc() from time to time if you need to.
