There are a lot of changes in the jake forest, one of which is storing 
the classes/resources for all modules in one jimage container. This 
should transparent to you, there is no need to every look in the lib/** 
tree. In particular, it will break things really badly if you copy or 
move jimage files between builds.

They will be forced to either eliminate the internal use or go modular from the start? Then the addExports will work. If I’m understanding that error message correctly.
If you feel strongly that the com.apple.eawt APIs should be exported in 
JDK 9 then you need to read JEP 260 [1] and make a case for adding the 
Apple APIs to the list.
