Robert:

This is a known problem and is being fixed.

JCE 1.2 beta1 was compiled with the latest "javac" version which
introduced a version number upgrade (which will be backed out again
before FCS). We are going to release another version of JCE 1.2 beta1
that was compiled with the compiler available in JDK 1.2 beta4
today. This release will be named JCE 1.2 beta2.

Sorry about that.

Thanks,

Jan
