Adding -XX:+VerifyBeforeGC -XX:+VerifyAfterGC didn't produce any
different result, still get one of the 3 before mentioned assertions.

Adding -Xlog:gc*=debug, I see that "Verifying Before GC" complete
without anything, and the last log line I get is:
[info ][gc,phases,start      ] GC(16) Phase 3: Adjust pointers
