NPE in Store  when running SELECT in a read-only database accessed via the classpath subprotocol
when authentication, authorization, and Java security are turned on
--------------------------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: DERBY-5615
                 URL: https://issues.apache.org/jira/browse/DERBY-5615
             Project: Derby
          Issue Type: Bug
          Components: SQL, Store
    Affects Versions: 10.9.0.0
            Reporter: Rick Hillegas


I get an NPE trying to select from a table on which I don't have select privilege. The database
is stored in a jar file accessed via the classpath protocol. BUILTIN authentication and sql
authorization are turned on in the database. Running under a Java security manager. I will
attach a repro. Here is the NPE:

Failed Statement is: select * from KIWI.t
