hello Jim,
Please let me know if you were able to resolve the issue. We were able to bypass the "The byte code of the class file has version 1.6. This is not supported by the JDO enhancer. Please compile with the option -target 1.5." by compiling the JDO classes with -target 1.5 in eclipse. But have run into other errors with "Persistence manager was closed" issue. Appreciate if you can let me know on your updates from the migration
Regards
PU
