Hi everyone,

I am porting hotspot to MIPS.  I meet a bug as follows.

In function Java_java_lang_ref_Finalizer_invokeFinalizeMethod,
value of jobject is right when call GetObjectClass and also right
before return from GetObjectClass . However,  it is wrong when
calling CallVoidMethod.   For example, It is changed from 0x3e0885d0
to 0x423ce794.
Thus, it results in an assert failure below.
------------------------------------------------------------------------------------------
  assert(SharedSkipVerify || obj->is_oop()) failed: sanity check
-------------------------------------------------------------------------------------------

I want to know who will change this value from return at GetObjectClass to
calling CallVoidMethod.  During this time, GC don't run.

Could anyone have an idea about this?


Thanks.

Yongqiang.
