These are issues a developer using XWork 1.1 will need to know when migrating to XWork 1.2:

• Configuration errors fail-fast - When XWork encounters errors loading xwork and validator configuration files, it will throw an exception rather than logging the error and continue processing.  The goal is that errors are more apparent to the developer and not buried in a log file somewhere, but it does mean XWork is less tolerant.  Please ensure all the appropriate files load correct and report any exceptions thrown that you feel shouldn't interrupt processing.
