I looked at the test.  As per the comments in the test, the tests are 
for testing using encryption using the encryptionKey.  I dont think it 
is trying to pass in an invalid key length for DES. 

So some possible options:
1)  how about changing the  algorithm to use AES , and in AES the cipher 
length is 16bytes.  Is that available with the 'SunPCKS11-Solaris'  ?
2)  change the key length for DES ( as you suggest).

I'll look at the derby code too and see if we can/should be doing 
something else for DES or other algorithms and report back.

Thanks,
Sunitha.
