Please see Ubuntu TruffleRuby failure at:
https://github.com/puma/puma/pull/2317/checks?check_run_id=896563842#step:7:579

The macOS TruffleRuby job passed.

Sorry about that, it looks like very weird transient, where it fails to unlock a lock it locked right above. So it's rather puzzling.
Could you rerun it?

@eregon

Sorry about that... Could you rerun it?

No problem, the tests do have intermittent failure issues, some of which may be caused by parallel testing.

I ran it it my fork with the same seed, and it passed:

Small revision to better align MRI & JRuby SSL code.

@JohnPhillips31416

Re the discussion in your PR #2302 (which should be merged soon), I've tried to add Puma::MiniSSL::Engine#init? and Puma::MiniSSL::Engine#shutdown in a manner that is similar to the MRI code. I also enabled all the SSL tests for JRuby.

It's passing here. If you have time, could you have a look at it? Some of the logging is different, I need to look a that some more, but some may also be due to differences in how Nio4r handles TCP/SSL/Unix sockets...

Looks fine, I don't see any issues.

@MSP-Greg can you rebase?

@nateberkopec what about merging in this one? should make us not see

Error in reactor loop escaped: undefined method `init?' for #<Puma::MiniSSL::Engine:0x3fffddf3> (NoMethodError)

in the output from the jruby tests, which would be nice (example)
