After some analysis this seems to be a duplicate of JDK-8139424. We haven't seen this assert after the fix for that and it seems likely that this assert is also caused by having a reference to an humongous object that has been eagerly reclaimed even though it should have. Both G1 occurrences show references that point to the start of a free region and the gc log shows that eager reclamation have occurred just prior to the GC where the assert is hit.

Note that the related JDK-8138705 is on Parallel GC, not G1.

This bug may relate to JDK-8138705. Same tests different assert.
