HIbernate reflection optimization with javassist MUCH slower than in previous versions with cglib
-------------------------------------------------------------------------------------------------

                 Key: HHH-2867
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2867
             Project: Hibernate3
          Issue Type: Bug
          Components: core
    Affects Versions: 3.2.3
            Reporter: MG


Hibernate reflection optimization with javassist MUCH slower than in previous versions with cglib,
and there is no way to set it to use cglib anymore

I'm setting 
hibernate.bytecode.provider=cglib
in hibernate.properties 

but it is still using javassist

     [java] 10:42:00,675 INFO  [Version] Hibernate Annotations 3.2.1.GA
     [java] 10:42:00,722 INFO  [Environment] Hibernate 3.2.3
     [java] 10:42:00,737 INFO  [Environment] loaded properties from resource hibernate.properties: {hibernate.jdbc.use_streams_for_binary=fal
se, hibernate.bytecode.use_reflection_optimizer=true, hibernate.bytecode.provider=cglib}
     [java] 10:42:00,737 INFO  [Environment] using bytecode reflection optimizer
     [java] 10:42:00,737 INFO  [Environment] Bytecode provider name : javassist
     [java] 10:42:00,753 INFO  [Environment] using JDK 1.4 java.sql.Timestamp handling


Please, check sample code in
http://jira.jboss.com/jira/browse/JBSEAM-1977
which compares cglib with javassist optimizations

cglib beats JDK 5 reflection almost 10 times
javassist performs even slower than JDK 5 reflection
