Hi!

Just to close the subject, could you please respond to the letter I send to you 
on Sept 2.

The patch (doing the same thing that was excluded by you) is attached.

ChangeLog entries:
        * gnu/javax/crypto/prng/CSPRNG.java (getSystemInstance()): Ignore
        ClassCastException as well.

Thanks.
