[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-5147) EnumType speed up in initEnumValues()

EnumType speed up in initEnumValues() ------------------------------------- Key: HHH-5147 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5147 Project: Hibernate Core Issue Type: Patch Components: annotations Affects Versions: 3.6 Environment: Hibernate 3.5.1, Sun JDK 1.6.0_18 Reporter: Ondrej Medek Assignee: Hardy Ferentschik Priority: Minor Attachments: EnumType.java.patch 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.
