 303                 if ("true".equalsIgnoreCase(atts.getValue("Multi-Release"))) {
 304                     return true;
 305                 }

This can be simplified to
   return "true".equalsIgnoreCase(atts.getValue("Multi-Release”));

MRJarWarning.java test
  66         defaultAttributes.putValue("Created-By", "1.8.0-internal (Oracle Corporation)");  

I suggest to drop “(Oracle…)”

  82         // jdeps still recognizes a mult-release jar.

typo: s/mult/multi

Otherwise looks good.
