]
Steve Ebersole closed HHH-2867.
-------------------------------
Resolution: Rejected
Oh, and btw; have you actually looked at the code for
org.hibernate.bytecode.javassist.FastClass? Might help you understand why what you are
doing is so slow ;)
Note that we do not use that org.hibernate.bytecode.javassist.FastClass#invoke method, nor
is it really intended for use (he just added it for completeness compared to the cglib
API). If you seriously want to do this, you would need to write the necessary calls to
the javassist APIs to actually create the optimization code (ala the 'fast
method').
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
Attachments: ReflectionTest.java
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

[java] 10:42:00,737 INFO [Environment] Bytecode provider name : javassist

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
