During Bigapps and adhoc testing this crash occured several times.

This crash is reported by jni* gc tests. However it often is hidden by another crash:
"assert(new_obj != 0 || obj->mark() == markOopDesc::prototype() || (UseBiasedLocking && obj->mark()->has_bias_pattern()) || obj->is_shared(),"should be forwarded")"


Here is the part of the hs_err:
