CodeTools proposal: "jdk-microbenchmarks"

[Eric Caspole]

Hi Stuart,
We deliberately moved JEP-230 back to candidate out of 9 due to resource 
constraints and that situation will continue. In order to make the 
benchmarks available and useful in OpenJDK, placing them in code-tools 
is the best solution for the time being. Maybe in the future JEP-230 can 
be worked on more actively where the benchmarks can be in the jdk source 
tree.
Regards,
Eric
