2.3.0 version not published for jruby

[keegangroth]

It looks like 2.3.0 was not published for java (I can see this version was released tody, but can't tell if the release is still in progress or not), which causes it to fail to install on jruby with

.../.rvm/rubies/jruby-9.2.8.0/lib/ruby/include/ruby.h:1:2: error: JRuby
does not support native extensions
#error JRuby does not support native extensions

Reproduction is to install jruby and do gem install json -v '2.3.0'. Version 2.2.0 installs correctly.

2.3.0 java appears to be published now
