OpenSSL::ASN1::Integer#value returns Bignum and not OpenSSL::BN #12

I encountered an error when running JRuby 1.6.5/1.6.4 with Capistrano: "(OpenSSL::PKey::DSAError: bad sig size)" I found this ticket filed with net-ssh that looked like a similar issue. I did some digging and saw the difference between JRuby and MRI was that the OpenSSL::ASN1::Integer#value method returns Bignum under JRuby versus the OpenSSL::BN in MRI. It looks like this is a problem in either jruby-openssl or possibly bouncycastle. I posted a workaround to the net-ssh ticket until this is fixed.

Thank you. Confirmed the problem as follows.

% ruby -ropenssl -e 'p OpenSSL::ASN1.decode('
% jruby -ropenssl -e 'p OpenSSL::ASN1.decode('
