This has started happening since RC15, not in RC14.

To reproduce:

git clone https://github.com/rack/rack.git
cd rake
bundle
rake test

RC15 + nightly

The same issue when I try to run gel tests...

[deepj]

@eregon Hello, it would be possible take a look at this, please?

[deepj]

@chrisseaton @eregon Can you take a look at this, please? I've seen more problems with uninitialized constant kind of problems.

[eregon]

OK, I'll try to take a look and reproduce.

[deepj]

@eregon the same issue has Falcon. See https://travis-ci.com/socketry/falcon/jobs/217858985

[eregon]

@eregon the same issue has Falcon. See https://travis-ci.com/socketry/falcon/jobs/217858985

I think that's unrelated and just caused by the first exception (#1715).

[rafaelfranca]

This should be fixed now. Rack test suite is green with the master branch.

[deepj]

@rafaelfranca I can't find it in changelog. In what commit it was fixed?

[eregon]

@deepj It's not fixed in 19.3, which the 20.0 milestone reflects.
I think https://github.com/oracle/truffleruby/pull/1779 fixed this.

[rafaelfranca]

Yes, that is the fix
