OpenSSL::X509::Certificate and OpenSSL::PKey::RSA constructors don't accept File objects

I opened an issue on Github but wasn't sure which bug tracker is preferred, so I'm putting it here as well.

In Ruby (at least 1.9.x) the OpenSSL::X509::Certificate and OpenSSL::PKey::RSA constructors accept a File or String, such as:

OpenSSL::X509::Certificate.new File.open("/path/to/my.crt")
OpenSSL::X509::Certificate.new File.read("/path/to/my.crt")

However, JRuby (at least 1.6.5 and 1.6.7) only accept a String:

OpenSSL::X509::Certificate.new File.open("/path/to/my.crt")  #=> TypeError: can't convert File into String
OpenSSL::X509::Certificate.new File.read("/path/to/my.crt")   #=> this works

I believe the error created when passing a File to the OpenSSL::X509::Certificate constructor comes from X509Cert which in turn calls OpenSSLImpl. – the call to "arg.toconvertToString" seems to be the problem.

I believe the error created when passing a File to the OpenSSL::PKey::RSA constructor comes from here – the call to "arg.toconvertToString" seems to be the problem.
