395                     // Copy TOP files of the "java.base" module (only)
396                     if ("java.base".equals(file.moduleName())) {

It may be better to throw an InternalError for any entry other than 
“java.base”.

Otherwise looks good.  You can fix this before you push.  No need for a new webrev.
