Failing to properly codegen enums with certain IDs

[namantash]

Execution of codegen for

enum EnumCodeGenTest {
    NAME_1 = 1000
    NAME_2 = 10000
    NAME_2 = 102
}

Produces

public enum EnumCodeGenTest {
    NAME_2(102),NAME_1(1,000),NAME_2(10000); // won't compile
    private final static Map<Integer, EnumCodeGenTest> map = new HashMap<Integer, EnumCodeGenTest>();
    static {
        map.put(102, NAME_2);
        map.put(1,000, NAME_1);  // won't compile
        map.put(10000, NAME_2);
        }
    private final int value;
    private EnumCodeGenTest (int value) {
        this.value = value;
    }

    public int getValue(){ return value; }

    public static EnumCodeGenTest findByValue(int value) { return map.get(value); }
}

The PR should fix it. Please review.
