Description Andrew Johnson CLA 2012-01-17 06:59:10 EST 
From code inspection and testing Pass1Parser.readString() converts constant pool names to Strings using the default encoding, not UTF-8.
This means that if the file.encoding is not utf-8 then the conversion will be wrong.

Test by creating a dump from executing this code:
public class Abc {
   static int A\u00C0 = 3;
   int B\u00D0 = 3;
   static Abc x = new Abc();
   public static void main(String args[]) {
   }
}
and running MAT with -Dfile.encoding=8859_1

Solution is to convert bytes using UTF-8.
