Description

1. add decimal type in ReflectiveSchemaTest#EveryType

 public static class EveryType {
   ...
    public final String string;
    public final BigDecimal decimal;

    public EveryType(
        ...
        String string,
        BigDecimal decimal) {
       ...
      this.string = string;
      this.decimal = decimal;
    }

2. Reconstruct ReflectiveSchemaTest#CatchallSchema#everyTypes with the new constructor, for example you can't assign the decimal field 1.2.

3. Run ReflectiveSchemaTest#testOp()
4. Exceptions are as followings
