@tstuefe @iignatev 
On a question: Have we decided that the STL can be used now? 

Hi Thomas,
  I do most of my JDK work in Java, hence may have missed knowing the restriction of using STL.
I wonder if this restriction is only for source code, and not the tests. I did a quick search under "test/hotspot/gtest", and found many uses of std::, including the data structures. For instance, jfr/test_networkUtilization.cpp uses std::map, std::list and std::vector.

Thanks,
Misha
