Observation:
The testcase are not fully deterministic.

I have now noticed that sometimes when running the testcase
the output looks the same:
java -Xbatch -XX:+SharkTraceInstalls HelloLoop
Hello World!
...
Hello World! [0x67c7c2d0-0x67c7cfb8): sun.nio.cs.UTF_8$Encoder::encodeArrayLoop
(3304 bytes code)

Dumping core ...
Aborted

yet the top of the java stack is different, sometimes it are not even a
SHARK_FRAME at the top, in this case it was a INTERPERTER_FRAME:
