> Backporting JDK-8337981: ShenandoahHeap::is_in should check for alive regions. Fixes Shenandoah's implementation of the `CollectedHeap::is_in` function to not just check that oop is within the heap bounds, but to check that it is within the committed section of the heap. Ran GHA Sanity Checks, and local Tier 1, and Tier 2 tests. Patch is clean.
