This can be easily used for crashtesting (filtering out only tests with jvm crashes).

The use-case doesn't carry the weight of introducing and maintaining a SPI for arbitrary and distant test result mangling in the inards of `jtreg`. The aforementioned JUnit `TestRule` is a good example for a non-distant (think: test-local) way to influnce the result of a test in an understandable way.

In the light of the discussion above, I won't approve this pull request.

Let's discuss other approaches to achieve the goals expressed in https://bugs.openjdk.org/browse/CODETOOLS-7903519
