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:
