      Summary

      The Javadoc for BsonValue.isNumber and BsonValue.asNumber indicates that true is returned "if the value is a BsonNumber". However, BsonDecimal128 extends BsonNumber and returns false for isNumber and throws an Exception for asNumber()

      How to Reproduce

       

      Java Driver version: "4.4.2"

       
       

      @Test
      public void asNumber() {
        new BsonDecimal128(new Decimal128(1L)).asNumber();
      }
      
      @Test
      public void isNumber() {
        Assert.assertTrue(new BsonDecimal128(new Decimal128(1L)).isNumber());
      } 

      Produces failure:
