Spock: Bug: Heap error is swallowed in Spock 2, feature is skipped, subsequent features don't run

[treyturner]

Issue description

A Spock feature that throws an java.lang.OutOfMemoryError: Java heap space exception will have its exception apparently swallowed by Spock 2.0 (I tried both M2 and M4). The offending feature will be returned as skipped, and no subsequent features in the specification are executed.

By comparison, Spock 1.3 will throw the heap error, fail the offending feature, and still execute subsequent features, which are all more desireable behaviors.

I am happy to explain this or the MRE linked below further if/as needed.

How to reproduce

Here is a minimal reproducible example in the form of a Gradle project, which has subprojects for Spock 1.3 and Spock 2.0 so you can easily see the difference:

Thanks @treyturner, btw the MCVE was just

class OomSpec extends Specification {
  def a() {
    expect:
    throw new OutOfMemoryError()
  }
}

but thanks for providing that example project.
