-----------------------------------------------------------------

A number of "internal" {{com.sun}} classes will be removed, including Unsafe. 
These removals need to be handled or HBase will not be able to run on a Java 9 
runtime. Doing this in a backwards compatible way may be tricky. I'm not sure 
how the Java platform community will navigate to where they want to go while 
dealing with unfixable user code breakage and I hope we have an opportunity to 
provide pushback on changes if required. 

I don't think we need to do anything today beyond track what others in the 
ecosystem are doing, for example HADOOP-11123

> significant compatibility departure from earlier runtimes.
