Create RSA-Private key from params is not consistent with MRI OpenSSL realization.

[keklabs]

I have 2 issues when I tested creation of RSA-keys on MRI 2.2.1 and JRuby 1.7.21, and JRuby 9.0.4.0 with default jruby-openssl and with the newest jruby-openssl-0.9.16.

First: When used MRI, the following code is sufficient to create a private key based on the parameters:

 key = OpenSSL::PKey::RSA.new
key.n = 16392814382236358374286478730803635966603711995044711413386654394374880287878372336023310219369520823643014365109038249939771923112625957783519605641636158082722812184189890358562406335672039498139105719171672367833874466201684192375357453493553219779287031256753504682678244544469842055901221240242010672802266061038234693512631745482956828422293756194060107183438880064480485030426406255944643048653218232929571416141572226550298104151251626730276899490795429237649764313700744612730340304290991262155071464084535035491902714392752262555875756559291544731914349885459219342356167914776303057793750903380835015380701

key.private?  => true

The parameters key.dmp1, key.dmq1, key.iqmp are optional, could be calculated from others. JRuby-OpenSSL requires all parameters to be specified.

The second Issues is: The order of the parameters affects behavior in Jruby-Openssl.

Following sample generates only PUBLIC key:

The problem is only in jruby implementation, not in MRI.
