Hi Andy, I attached a file (sometests.conf). This is a configuration file executing only test cases of class "NewObjectIdInstance". You may adapt the entry "jdo.tck.classes" as appropriate. Please copy this file to ".../tck20/conf", then execute in tck20: maven -o -Djdo.tck.cfglist=sometests.conf runtck.jdori This runs the test cases of class "NewObjectIdInstance" for application identity and datastore identity. The run using application identity fails with 17 errors. You can ignore the NPEs (6 errors) for now. They are thrown because the enhanced code passes "null" as arguments to constructors of SingleIdentity classes. The remaining 11 errors indicate the problem which I'm interested in. I attached the log files of those runs for your convenience. Regards, Michael >>I sent a patch (Assertion-A7-A8.patch) containg the test case >>(NewObjectIdInstance.java) to jdo-dev today. I ran it with JPOX build >>"20050628.022915". This seems to be the latest build available under >>nightly builds.
