Subject [jira] Commented: (DERBY-2596) JDBC 4 statement.isClosed throws IllegalAccessError when used with EmbeddedXADataSource40
Date Tue, 01 May 2007 20:54:15 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2596?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12492944
] 

Stan Bradbury commented on DERBY-2596:
--------------------------------------

Mea culpa, my apologies - I failed to validate that the failing test was run in a reference
environment.  A beta version of JDK 6 was being used.  Thank you Dag and Knut for looking
this, sorry for the distraction.

Am closing this.
