    Modeshape REST occasionally gives null pointer exception response to JCR SQL2 query


      Hello, Hello I'm using  Modeshape 5.4.1 and  the REST API,  modeshape-web-jcr-rest-war,   to support both direct Get/Put/Post operations for content nodes, as well as through JCR SQL2.

      I've noticed that sometimes ModeShape or the REST API gets into a state where any JCR SQL2 query (via POST) will result in a null pointer exception.

      Restarting Modeshape is the only thing that currently seems to resolve the issue. Has anyone else encountered this behavior?
