AR-JDBC is (currently) a volunteer effort, it is not backed by any company ... You can contribute and make a difference for all JRuby on Rails sites out there.
Part of AR-JDBC is a native JRuby extension written in .java, compiling (or even
using) the project requires that you have javac on your path for building the gem.
This means a JRE isn't sufficient and you will be forced to install a JDK.
We encourage you to try looking into reported issues, esp. if the new issue is about (Rails) incompatibility with MRI - as it might be fixed with some copy-paste magic.
Please consider testing against master, if you're in doubt whether it might have been fixed already, change the following in your Gemfile :
gem 'activerecord-jdbc-adapter', :github => 'jruby/activerecord-jdbc-adapter'
Do not forget to include the following with your bug report :
-
AR-JDBC's version used (if you've tested against master mention it)
-
version of Rails / ActiveRecord you're running with
-
JRuby version (you might include your Java version as well) -
jruby -v -
if you've setup the JDBC driver yourself please mention that (+ it's version)
-
include any (related) back-traces (or Java stack-traces) you've seen in the logs
-
... a way to reproduce :)
You're code will end up on upstream faster if you provide tests as well, read on how to run AR-JDBC tests.
When fixing issues for a particular Rails version please be aware that we support multiple AR versions from a single code-base (and that means supporting Ruby 1.8 as well - esp. targeting 4.x we can not use the 1.9 syntax yet).
Please keep our test-suite green (been funky for a while and it's been hard-work getting in back to shape), while making changes, if they're related to an adapter covered by those.
❤️ JRuby-Up!
