Please note that the same test could also fails with the asserion:
# Internal Error (/tmp/jprt/P1/B/230259.et151817/source/src/share/vm/gc_implementation/shared/markSweep.inline.hpp:90), pid=24258, tid=2746694544
# Error: assert(new_obj != __null || obj->mark() == markOopDesc::prototype() || (UseBiasedLocking && obj->mark()->has_bias_pattern()) || obj->is_shared(),"should be forwarded")
or SIGSEV in another method :
 58 V [libjvm.so+0x207bd5];; oopDesc::size()+0x15
 59 V [libjvm.so+0x4e61d2];; G1ParCopyHelper::copy_to_survivor_space(oopDesc*)+0x12
 60 V [libjvm.so+0x4ed94f];; G1ParCopyClosure<false, (G1Barrier)1, false, false>::do_oop(oopDesc**)+0x3f

So please check that it is exactly this CR when reproduce it.

The report is:
