I am having problems getting JRuby 9.1.12 to run my Rails project. I was previously on 9.1.2, and that works fine. All I have done is updated JRuby, and now it fails.
To investigate, I created a test project, first using JRuby 9.1.2:
rails new testy --database postgresql cd testy rails g scaffold Location name:string
``
Location is a table in an existing database, so quicker for testing. I deleted the migration, copied across database.yml from my project, and edited secret.yml so it uses the same key as the tests. Then:
rake test warble
``
Then I put the .war into Tomcat and it works fine. So then JRuby 9.1.12:
gem uninstall -v 9.1.2 jruby-jars gem install -v 9.1.12 jruby-jars warble
``
I stop Tomcat, delete the old files, and put this new war in. Now I see this when going to a page in testy:

I have Googled the error, but found nothing, so I am a bit stuck! I am using Java 1.8.0.131 (32 bit), Tomcat 8.0.45 (32 bit), Warbler 2.0.4 on Windows 7 Pro.
Any help or suggestions appreciated.
