The fix per se is in lines: 3341-3343, but then I made some additional changes to the position where previous errors were reported at method JavacParser::variableDeclaratorRest. That was done for consistency with the new code. I could have done the other way but then users would have two error notifications for some code, one for the use of the restricted type per se and another one for the use of the variable or field so like:

Doing that adjustment has implied some changes to the golden file associated to test ParserTest. Also I added another case and did some additional editing to test SealedCompilationTests.
