When one of the arguments of lowestCommonSuperType is char_type and the other byte_type it returns null where it should return int_type.

possible fix:
       return t2;
     else if (t2.isSubtype(t1))
       return t1;
+    else if (t1 == char_type && t2.isSubtype(int_type))
+      return int_type;
+    else if (t2 == char_type && t1.isSubtype(int_type))
+      return int_type;
     else
       {
        // the only chance left is that t1 and t2 are ClassTypes.
