create_extension('authorityKeyIdentifier','keyid,issuer') fails #174
Description
In Ruby (OpenSSL, really), the "keyid" of "authorityKeyIdentifier" has an optional ":always" value.
However in JRuby openssl, it looks for "keyid:" and therefore fails when the optional value is left off.
The documentation is here: https://www.openssl.org/docs/man1.0.2/apps/x509v3_config.html
Note the example is just keyid,issuer.
