After install JRE 7u2b08, the AU version should be 2.1.5.2.
The AU version in registry key and ping values is set to 2.1.5.2 correctly.
But the version of AU files(jucheck.exe, jusched.exe, jaucheck.exe, jaureg.exe) is not 2.1.5.2, but 2.1.5.1. It should be 2.1.5.2 also.
The Au version will be changed to AU 2.1.5.3 in the AU digital signature's fix.
