Three builds have hung around the same place, near here:

  • rx.exceptions.ExceptionsTest > testStackOverflowIsThrown STANDARD_OUT
  • rx.exceptions.ExceptionsTest STANDARD_OUT

The logs can be seen at:

I have tried to replicate in the ExceptionsTest code but have not succeeded.

Anyone able to reproduce this? I haven't been able to.

I let testStackOverflowIsThrown run in a loop for 20+ minutes without issue.

Happened again here: https://netflixoss.ci.cloudbees.com/job/RxJava-pull-requests/1489/consoleText

But this looks like it has more logs:

I can't replicate this and no one has reported this in prod/dev usage, only Cloudbees, so I'm moving this to 1.0 and not blocking 0.20 on this.

What happens is that a StackOverflowError is thrown but the check for it close (the stack is still next to full) so the attempt to report it may again cause another StackOverflowError. So instead of causing an actual StackOverflow, we could just throw one similar to how ThreadDeath is tested. Btw. assertFalse(isComputerOn())?

I haven't seen this failure a long time so closing.
