Code review request: 7064075 Security libraries don't build with javac -Xlint:all, -deprecation -Werror

Thu Aug 4 00:10:24 UTC 2011

Those were the ones I was talking about- the serialVersionUIDs I 
mentioned were the ones generated by serialver.exe. The webrev doesn't 
have any of the pkcs11 changes yet (including the added serialVersionUIDs).

I'll wait for Brad's or Valerie's response.

Thanks,
Sasha
