Random test failure on jruby

We've been getting this for a while. I skipped the tests and the reenabled them again since I thought it was fixed. It's not apparently.

Good news is that the error message is now a bit more informative.

This is the failure:

I guess we can skip this again, but I'd like to report the issue to jruby first. I'll try to do that tomorrow and link it to this ticket.

This issue is related to:

I will abide by the code of conduct.

Another one: https://github.com/rubygems/rubygems/runs/562058361

It happened again, but on a different test of the same file: https://github.com/rubygems/rubygems/pull/3506/checks?check_run_id=577376490.

Setting this as blocked until webrick supports jruby.

@ioquatix

This looks like the typical race in WEBrick during shutdown, where both the server thread and the thread calling shutdown try to close the same pipe, which can result in EBADF (or worse, writing to the wrong fd!). On MRI it's an IOError instead because (I think) the GIL enforces close to happen one after another.

I think we need to fix this in webrick upstream, that shutdown pattern seems fundamentally broken.

cc @ioquatix who also saw this recently
cc @headius who probably already saw this bug

I'll close this ticket since we've been skipping these specs since #3507. We can try unskip them once jruby fully supports webrick.
