[jira] [Commented] (DERBY-5615) 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
[ https://issues.apache.org/jira/browse/DERBY-5615?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13207917#comment-13207917 ]
Mike Matrigali commented on DERBY-5615:
---------------------------------------
can you post the full derby.log that has the error. Sometimes there is more info there, especially if some of the background threads are getting
errors and then affecting the client thread.
That line in my client is:
at org.apache.derby.impl.store.raw.data.BaseDataFileFactory.openContainer(BaseDataFileFactory.java:661)
FileContainer container = (FileContainer) containerCache.find(identity);
So it looks like containerCache went null. A quick search leads to one way this can happen is if some corrupt level error is encountered, then
we mark everything null as we don't know what state the db is in and need to insure all clients exit.

> 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:
