      Description

        I run `jhsdb jstack --mixed` to JShellToolProvider process, then I saw <Unknown compiled code> in the stack as below:

        ```
        ----------------- 4741 -----------------
        "process reaper" #13 daemon prio=10 tid=0x00007f959c328000 nid=0x1285 runnable [0x00007f9578025000]

        ```

        0x7f958c601d79 is native method. jstack mixed mode should handle it.
