      Description

      When extending java.lang.BigInteger, using an obj of that child class as argument to a method with BigInteger parameter causes a MissingMethodException. Similar variations with BigDecimal or Number work fine.

      Sample:

      public class MyDecimal extends java.math.BigDecimal {
          public MyDecimal(String s) {super(s);}
      }
      
      public class MyInteger extends java.math.BigInteger {
          public MyInteger(String s) {super(s);}
      }
      
      class Expression {
          public int takeNumber(Number a) {return 1;}
          public int takeBigDecimal(BigDecimal a) {return 2;}
          public int takeBigInteger(BigInteger a) {return 3;}
      }
      
      Expression exp = new Expression();
      assert 1 == exp.takeNumber(new MyInteger("3")); //works fine: 1
      assert 2 == exp.takeBigDecimal(new MyDecimal("3.0")); //works fine: 2 
      assert 3 == exp.takeBigInteger(new MyInteger("3")); //MissingMethodException
