Subject [jira] Updated: (DERBY-5113) Intermittent failure in BlobSetMethodsTest on Java 7: Unable to set stream: 'Reached EOF prematurely; expected 1,024, got 0.'
Date Sun, 13 Mar 2011 08:39:59 GMT

     [ https://issues.apache.org/jira/browse/DERBY-5113?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Knut Anders Hatlen updated DERBY-5113:
--------------------------------------

    Attachment: derby-5113-1a-test.diff

The attached patch adds a tearDown() method to AccessTest. The database properties modified
by the test are now cleared after each test case. DatabasePropertyTestSetup couldn't be used
for this since the properties are set to different values in each test case, and not globally
for the whole test which is how that decorator is normally used.

Committed revision 1081059.

> Not sure if this is a test issue, a product issue or a JVM issue. It started happening
when JDK 7 was upgraded from b116 to b131 in the nightly tests. I haven't been able to reproduce
the failure in my environment, but it happens frequently in the nightly testing. For example
here:

> The problem does not appear to be the reordering of the test cases that we've seen in
many other tests when running on Java 7 b131. According to the traces printed to the test
log (for example in the above mentioned URL), this failure is also seen in the cases where
the test cases run in the same order as on most other platforms.
