Since you specified BY DEFAULT that means you can import TABLE1 using the existing id values so that when you import TABLE2 you shouldn't have any referential integrity issues. But, of course, you'll want to export the id values from TABLE1. I was able to do this using Derby's SYSCS_UTIL.SYSCS_IMPORT_DATA procedure.
