Intermittent OutOfMemoryErrors in BasicSetup.testTriggersWithLOBcolumns()
-------------------------------------------------------------------------

                 Key: DERBY-5277
                 URL: https://issues.apache.org/jira/browse/DERBY-5277
             Project: Derby
          Issue Type: Bug
          Components: Test
    Affects Versions: 10.9.0.0
            Reporter: Knut Anders Hatlen


Seen many times in the JDK 7 tests lately, and also in the Tinderbox. First occurrence was
here: http://dbtg.foundry.sun.com/derby/test/Daily/jvm1.7/testing/testlog/sol32/1134678-suitesAll_diff.txt

(There had been no commits in the last two days before this test run, so it's difficult to
say if a recent change caused it.)

The test case has a comment that says that it should never read the LOB into memory, but according
to the stack trace, that's exactly what's happening:

Caused by: java.lang.OutOfMemoryError: Java heap space
