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

```
----------------- 4741 -----------------

```

0x7f958c601d79 is native method. jstack mixed mode should handle it.
Comments
Fix request (13u): The change applies cleanly, sanity check with tier1 tests.

Fix Request for 11u: This patch fixes to show native method call in `jhsdb jstack --mixed`. It can work on tier 1 tests on submit repo, and can be applied straightly to 11u-dev.
