My server had no problems deleting temporary directories and files upon server shutdown until recently when I was configuring my server to persist JMS messages to a new datasource (MySQL) I declared. I was deleting and updating files in the jms, conf and deploy directories while the server was running (I unfortunately forgot to shutdown the server). Now, when I shutdown the server, temporary files and directories could no longer be deleted. Have I corrupted my server? I've tried installing a new server but get the same result, so I'm thinking there must be something wrong with my jdk. I must have corrupted something somewhere.
