Once we are further along with modules in the JDK 9 then I expect that 
-Xbootclasspath/p will go away (to be replaced by an alternative 
facility to override the classes in modules that are linked into the 
runtime image).  So is this wsgen and wsimport code only used with JDK 
6? Maybe that is okay but at the same time I would hope these APIs could 
leave JDK 6 behind some day, otherwise it makes it impossible to use 
language features and APIs.

The update looks okay to me. I guess we'll have to see if other changes 
are required as we move forward. Also thanks for the explanation about 
JavacompilerMessages.java being auto-generated, there isn't anything in 
the header that makes this obvious (maybe the plugin that you mentioned 
could be updated to generate something into the header?).
