Method Missing: org.jruby.RubyInteger.int2fix #5216
Description
Environment
Upgrading a project from jRuby 9.1.17.0 to 9.2.0.0 on OS X and Linux in a CI Docker container:
% jruby -v
jruby 9.2.0.0 (2.5.0) 2018-05-24 81156a8 Java HotSpot(TM) 64-Bit Server VM 25.152-b16 on 1.8.0_152-b16 +jit [darwin-x86_64]
% uname -a
Darwin inquanok 17.6.0 Darwin Kernel Version 17.6.0: Tue May 8 15:22:16 PDT 2018; root:xnu-4570.61.1~1/RELEASE_X86_64 x86_64
(My environment generally has JRUBY_OPTS=--debug set, but I don’t believe that is relevant.)
The project is a Rails 5.1 application using jruby-pg, and the error occurs on environment initialization, the example below is starting RSpec, but a rails console will also trigger it. [example updated because the rails console error is easier to read]
Expected Behavior
jRuby 9.1.17.0 has no trouble loading jruby-pg in a rails context. I can provide a link to a stripped down repository exhibiting the issue, but it’s a pretty easy reproduction case, I doubt even Rails is required in the mix.
Actual Behavior
My first suspicion was that jruby-pg needed to be updated to work with jRuby 9.2, but the INT2FIX macro still exists in MRI 2.5, so I suspect this may be a more general issue. Since @headius is the author of jruby-pg, I figure he’ll know best where it should be fixed. I’m happy to close this issue and reopen it over there if I surmised incorrectly.
