I don't think it's appropriate to close this issue referring to the jdbc4 test.
Looking at suites/AllPackages.java it appears this test currently only runs with jvms that support jdbc4 (i.e. jdk1.6 (and up, I assume)):
// Suites that are compiled using Java SE 6 target need to
// be added this way, otherwise creating the suite
// will throw an invalid class version error
Maybe ClosedObjectTest can be run with jdk14/jdk15...But just closing this is not ok, I think.
However, for priority/urgency of this JIRA task: the StmtCloseFunTest now runs under the JDBCHarnessAdapter...
