        examples/java/calc/Calc.java:1531: warning: [deprecation] 
Integer(String) in Integer has been deprecated
              yylval = new Integer(st.sval);
                       ^
    
    * examples/java/calc/Calc.y, examples/java/simple/Calc.y,
    * tests/calc.at, tests/scanner.at: Use Integer.parseInt.
