I disabled the logstash Gem and the installation works then. https://travis-ci.org/pxlpnk/lograge/jobs/69362086
Could the problem be in fetching the Gem or something in the gemspec?

Hmm...I'm trying to reproduce it by bundle installing from that PR and it's not blowing up for me. Are you able to reproduce the exception locally? We need more information.

I had the same issue with a jruby-head build (via RVM) this afternoon.

@headius I am currently struggling with setting up a vm that is like the travis ci one.
What would you need on information and how do I get it?

@pxlpnk You can request SSH access to an instance for 24 hours by emailing Travis CI support. Once in there you can run the same sequence of commands, but for the bundle install we can try a few flags to get more information:

• --verbose or other bundle flags that would make it print out the exceptions
• with and without jruby flag -Xbacktrace.style=full which includes normally-omitted Java backtrace lines

I'll be on IRC today if you want to work together on this.

@cheald If that is indeed the same error, it may be related to a fix we made to prevent this error. What rev is that build?

Unfortunately I won't get to this today. I will ping their support and see if I can get SSH access and run it with -Xbacktrace.style=full

Using --verbose didn't yield any result as it can be seen here: https://travis-ci.org/pxlpnk/lograge/jobs/69359540#L181

$ jruby -v
jruby 9.0.0.0-SNAPSHOT (2.2.2) 2015-07-02 10be3bb OpenJDK 64-Bit Server VM 25.25-b02 on 1.8.0_25-b18 +jit [linux-amd64]

FWIW, this is failing when I try to run rake from my Manticore project - https://github.com/cheald/manticore - you can probably clone it and bundle install/rake to repro it. I'm working on rebuilding jruby-head right now to re-test.

Full reproduction steps here: https://gist.github.com/cheald/81b0189bb64dabcff8aa

@cheald Great, thank you!

I was unable to reproduce with my working copy of JRuby, but I'll try against RVM now.

The fix is in! Please confirm with latest JRuby head.

Still breaks on travis. Do you know how often the jruby head builds get updated from their side? /cc @rkh
