Subject [jira] Created: (DERBY-1754) sqlAuthorization mode causes Null Pointer Exception during ALTER TABLE
Date Thu, 24 Aug 2006 06:49:12 GMT
sqlAuthorization mode causes Null Pointer Exception during ALTER TABLE
----------------------------------------------------------------------

                 Key: DERBY-1754
                 URL: http://issues.apache.org/jira/browse/DERBY-1754
             Project: Derby
          Issue Type: Bug
          Components: SQL
    Affects Versions: 10.2.2.0, 10.3.0.0
            Reporter: Bryan Pendleton


I'm concerned about the effect that I saw from setting
derby.database.sqlAuthorization=true in my environment.

I tried making a one line change to the properties used by the
altertable.sql test (see inline diff below), and then running

  java org.apache.derbyTesting.functionTests.harness.RunTest lang/altertable.sql

The result was a horrendous diff in which the altertable test ran
for a little bit, then printed a Null Pointer Exception, then
started saying

  ERROR 40XT0: An internal error was identified by RawStore module.

over and over for the rest of the test.

Below I've pasted the one-line diff that I applied, and I've also
pasted the stack trace for the Null Pointer Exception and for the
first of the subsequent 40XT0 messages.

What I'm hoping is that someone will say either:
 - "that's a usage error; you can't just set that property like that", or
 - "that's a bug, please file it"

By the way, this is with the current head of trunk.

thanks,

bryan
