JavaFileManager UnsupportedOperationException

[Jonathan Gibbons]

JavaFileManager has some new methods whose default implementation is to 
throw UOE.

Are you providing your own full custom file manager?  If you are, and 
you are using it in a module-oriented compilation (i.e. -target 9) then 
you need to provide the new methods.
