      Description

      I tried to get thread dump via jstack command on CLHSDB. But it was failed as below:

      {{
      Caused by: sun.jvm.hotspot.types.WrongTypeException: field "_stack_traversal_mark" in type nmethod is not of type jlong, but instead of type long

      }}

      I think this exception is caused by JDK-8186837.
      This changeset has changed the type of `nmethod::_stack_traversal_mark` to `long` from `jlong`.

      SA should follow this change.
