compatibility of JCE1.2.2 and JCE1.2.1 is broken for keystore

Jce1.2.2 compatibility is broken with Jce1.2.1. My test use jce1.2.2. to create a keystore and store some secret keys, then write to "jceks". Then using jce1.2.1 to load it. an IoException is thrown.

How to reproduce:
1. untar the attached test.tar
2. sh Run.sh

You will see:
=========== Using JDK 1.3.1 ==========
=========== create under jce1.2.2 ==========
=========== Using JDK 1.3.1 ==========
