Please review the change that fixes an intermittent issue. The problem here is that a bitwise-AND (&) operator was used in the condition instead of a logical AND operator (&&). As a result pending_thread->is_thread_fully_suspended() is always evaluated regardless of the value of at_safepoint variable.
