Subject [jira] [Commented] (DERBY-5988) Instability in DataSourceTest: some test fixture orderings makes test_jdbc4_1 fail
Date Mon, 12 Nov 2012 00:17:13 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5988?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13495054#comment-13495054
] 

Dag H. Wanvik commented on DERBY-5988:
--------------------------------------

Note: The repro shows this using the embedded driver, but I actually only saw this in the
original test suite for the client driver, probably because the embedded driver is *always*
loaded as part of the call to CleanDatabaseTestSetup used by defaultSuite. In the repro I
don't do that so the error also manifests for embedded driver.
