[jboss-jira] [JBoss JIRA] Commented: (JASSIST-28) javassist enhancement failed on deserializing hibernate proxies

Shigeru Chiba commented on JASSIST-28:
--------------------------------------

It turned out that we must modify a source file of Hibernate.
JavassistLazyInitializer.java is the new source file that has to be substituted.

Hibernate with that source file and the latest snapshot of Javassist shows
as good performance as Hibernate+cglib.  However, both cglib and Javassist
cannot finish your test code; both of them hang up.
