Maybe we should use platform API for concurrency? https://github.com/JetBrains/intellij-community/blob/a555f2f6c8cc4ed54462362b737687859cca318b/platform/util/src/com/intellij/util/concurrency/Semaphore.java and others

I am not sure how that Semaphore works as it seems like both waitFor() and down() need to be called but that would mean there is a race condition.. Do we need an IntelliJ specific Semaphore instead of the standard Java one?

Ok, I understand the change, one thing - if compileAndReload somehow fails and do not publish finished event we will have lock never released?

[Artur-]

Yes, then no further compiles will take place and that is why it uses an executor service so that if this would happen, then IntelliJ won't freeze completely but only the started thread. At some point it will run out of threads though.

Maybe we should have a timeout

Now it hopefully waits up to 30s, gives up and proceeds
