There is no submit repo for JDK updates.

I think it is maintainer's duty to decide if testing was enough (this is why Fix Request requires
[1] to spell out what testing was done). That said, it seems the more tests you run, the more less
chance backport would be problematic.

In my mind, the bare minimum is to run the regression tests supplied with the backport, and also the
tests for the component you push to. For example, for
https://bugs.openjdk.java.net/browse/JDK-8218192 that you have on your plate, I'd run hotspot_gc:

$ make images run-test TEST=hotspot_gc

Passing tier1 in fastdebug (and release, if you have time) seems to be a good sanity test for all
patches too:

$ make images run-test TEST=tier1
