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, so my suspicion is a bug in JRuby.

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:

Not convinced #4717 is the same issue, as that seems to be specific to 9.1.12. I have gone back through jruby-jars versions, and I get the same issue with 9.1.9, 9.1,10, 9.1.11. It does work with 9.1.8 (and presumably earlier versions).

@F2Andy the stacktraces are exactly the same here and in #4717
and the orignal report also stats it fails to work with 9.1.9 and works with 9.1.8

Sorry, I miss read it, and thought it was an issue with 9.1.12.

Could it be related to #4734 ?

@HarlemSquirrel I don't think so; this appears to be an character-encoding problem.

headius commented Aug 24, 2017

Ok, so basic cause here is that we've got an internal encoding (the default encoding used for symbols and strings in memory) that can't be associated with a Java Charset needed to convert back and forth to Java strings. But instead of reporting the name of the encoding, it's passing a null charset to String.getBytes, which also does no null check and then blows up.

I tried to simulate this with an encoding Java doesn't support, ISO-8859-14, but we get a different error.

# encoding: ISO-8859-14

puts :ø.encoding
$ jruby blah.rb

                        main at org/jruby/Main.java:204

This is the same path as in the reported exception, but before it passes the null it gets an error from Java indicating the encoding is not supported. So the path causing the reported issue must be from an encoding that we don't even try to associate with a Charset.

I'm looking into it.

headius commented Aug 24, 2017

Ok, that got me closer. We do not associate at least the Windows-125* encodings with any Java charset, so they just return null.

I'm discussing possible fixes and improvements to this logic with @enebo now.

headius commented Aug 25, 2017

Ok I think the fix is fine but updating jcodings is not a good idea for a 9.1.x release. jcodings has had numerous changes to support Ruby 2.4 features, some of which are slightly incompatible with JRuby 9.1.x's logic. I will instead do the same fix as a workaround in 9.1.13.

Work around jcodings null charsets by doing a second lookup.
bfc5ee4 
This is equivalent to fixes made for #4716 in jcodings 1.0.25, but
other changes in that version made it too risky to upgrade in
JRuby 9.1.x. The code here wraps jcodings with the appropriate
logic rather than updating.
