ExecutionEnv is not shutdown, eventually leading to OOME

specs2 v5.2.0
running tests in sbt without fork hangs on to classloader which eventually blows up Metaspace

specs2/common/shared/src/main/scala/org/specs2/concurrent/ExecutionEnv.scala

Line 13 in ad4e1d1

def shutdown(): Unit = ()

for some reason is a noop....

That's bad indeed. I'll try to fix this as soon as I can.

@etorreborre is https://github.com/OlegYch/specs2/blob/103e69279d24137755ae7458b860b67455423379/common/shared/src/main/scala/org/specs2/control/Action.scala#L63 supposed to throw away last?

also https://github.com/OlegYch/specs2/blob/751ec0bd90b4d49a9669501b362f771b87b61dbf/common/shared/src/main/scala/org/specs2/control/Operation.scala#L154
and some other places...

@OlegYch I have made some good progress during the week-end but I cannot yet release a fix now. I hope I'll fix it this week.

@etorreborre sounds nice
here is a sample project https://github.com/OlegYch/specs-sbt

Hi @OlegYch. I just released specs2-5.5.0. Thanks for your sample project, I can confirm that it works fine now.
And thanks for all your pointers, I indeed had to patch some serious holes.

cheers 🍻
