Subject [jira] Updated: (DERBY-4671) Embedded driver does not work with jbossCache
Date Fri, 21 May 2010 14:08:16 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4671?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Knut Anders Hatlen updated DERBY-4671:
--------------------------------------

    Attachment: derby-4671-1a.diff

The attached patch fixes the NullPointerException by reintroducing some code that was removed
in the DERBY-4420 fix. Now the type will be initialized for dynamic parameters in the select
list of INSERT INTO ... SELECT FROM statements, so that we don't run into a NullPointerException
later in the compilation. The patch also adds a regression test case for this bug.

I'm running the full regression test suite now.
