Bouncycastle 1.51 causes load error: jopenssl/load -- java.lang.VerifyError: Bad type on operand stack

[cheister]

The 1.51 Bouncy Castle release http://www.bouncycastle.org/releasenotes.html causes a load error.
From the release notes they claim "Some changes have affected the return values of some methods" which I suspect is to blame
The error is:

[WARNING] ERROR:  Loading command: install (LoadError)

currently jruby-openssl works with bouncy-castle version 1.47 to 1.50

eventually we will get to 1.51 but of course you are welcome to help here
with PR ;)

unintentionally some work got in at 7fe42fd and 2684a83 we'll accept further 1.51 related issues as we start actively testing against 1.51 after the (hopefully 0.9.6) release

Isn't one potential resolution for this sort of issue to prefix BC's package names so that they don't clash with a different version? :/
