Subject [jira] Commented: (DERBY-3842) Convert "org.apache.derbyTesting.functionTests.tests.store.holdCursorExternalSortJDBC30.sql" to junit.

Tiago R. Espinha commented on DERBY-3842:
-----------------------------------------

You're right Kathey. I have built the code and jars in insane mode and the test fails.

Just some more info that I have been able to acquire through testing:
- The sortBufferMax *is* being set now. I have been able to confirm this through direct output
from the ExternalSortFactory.java and also through the getSystemProperty method. This value
is being set to 5 like it should.

- When I'm running an insane build, or if I simply omit the derby.debug.true, the tests passing
or failing is seemingly random. They fail most of the times but randomly one of them will
pass, which I am truly clueless about. I have even set up the test so that it creates two
separate tables now, since there's a test that requires additional data to be added.

When the said tests fail though, I have confirmed that the sortBufferMax is indeed still set
to 5, but the statistics just show that an internal sort was done rather than an external
one. Weirdly enough, if the debug is set to true, the tests pass all the time. I even made
several consecutive runs of the test just to be sure and it is a 100% pass rate.

Does anyone have any ideas as to why this is happening?
