Kevin Barrett updated THRIFT-489:
---------------------------------

    Attachment: jvalidv.patch

This patch fixes VALID_VALUES generation to include all identifiers, and formats the output a little.

> Java client enum validation code is rejecting any value other than those explicitly assigned inside the enum declaration.  For example:
> {noformat}
> enum testEnum {
>     valueZero = 0,
>     valueOne,
>     valueTwo
> }
> {noformat}
> generates the following code (excerpt):
> {noformat}
> public class testEnum {
>   public static final int valueZero = 0;
>   public static final int valueOne = 1;
>   public static final int valueTwo = 2;
>   public static final IntRangeSet VALID_VALUES = new IntRangeSet(valueZero);
>   public static final Map<Integer, String> VALUES_TO_NAMES = new HashMap<Integer, String>() {{
>     put(valueZero, "valueZero");
>     put(valueOne, "valueOne");
>     put(valueTwo, "valueTwo");
>   }};
> }
> {noformat}
> If all enums are given explicit values, VALID_VALUES is initialized as follows:
> {noformat}
>   public static final IntRangeSet VALID_VALUES = new IntRangeSet(valueZero, valueOne, valueTwo);
> {noformat}
> If no explicit values are assigned, VALID_VALUES is initialized with no parameters.
> Verified with r764072 and r771969.
