Description
If ModeShapeEngine.undeploy() on a repository using the local index provider is called from a JVM shutdown hook, e.g. in the case of a spring managed scenario, then sometimes MapDB throws an IllegalArgumentException "already done".
The problem is that it is possible that the shutdown hook registered via MapDB by LocalIndexProvider's use of DBMaker.closeOnJvmShutdown() will be called prior to the call to undeploy() and subsequently LocalIndexProvider.postShutdown().
This should be as simple as adding a guard using db.isClosed() to postShutdown().
