> Hi,
> I have simplified and sped up the method EnumType.initEnumValues(). See the attached patch. 
> Tested on Sun JDK 1.6.0_18
> Note 1: I do not know, why the author (Emmanuel Bernard?) has used reflection. Maybe the method Class.getEnumConstants() in not implemented by other JREs (IBM, BEA) or he just didn't know this method.? 
> Note: the method getEnumConstants() in SUN JRE does use the reflection to look for method "values()", too, but it's results are cached, so the second call to the getEnumConstants() is fast. And because the results are cached inside the Enum class itself, it does not cause any memory leaks like HHH-4317.
