Subject [jira] Commented: (DERBY-3618) Perform thread dump with ASSERTS with jdk 1.5 or higher
Date Wed, 28 May 2008 18:27:46 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3618?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12600558#action_12600558

Kathey Marsden commented on DERBY-3618:
---------------------------------------

Thanks Erlend for the patch.
-- need a license header for ThreadDump

-- AssertFailure
We can't use org.apache.derbyTesting.functionTests.harness.JavaVersionHolder in the engine
code. You can use org.apache.derby.iapi.services.info.JVMInfo instead.

I think that we can keep the System.out backup if there is no stream, but should check to
see if Monitor.getStream() is null instead of catching the NullPointerException.

I wonder if we could try testing this from within a stored procedure, from there there should
be a log stream present.

> It would be good to have a stack traces for all threads dump to the derby.log when an
assertion occurs with JVM's that support it.
