* jvmti.cc (THREAD_DEFAULT_TO_CURRENT): Clarify parameter list.
        (THREAD_CHECK_VALID): Likewise.
        (THREAD_CHECK_ALIVE): Likewise.
        (_Jv_JVMTI_SuspendThread): Call THREAD_CHECK_VALID on a Thread not
        jthread.
        (_Jv_JVMTI_ResumeThread): Likewise.
        (_Jv_JVMTI_InterruptThread): Likewise.

        (_Jv_JVMTI_DisposeEnvironment): Probably unwise to dereference an object
        that was just freed.
