Hi,guys
Recently my project needs to be moved to glassfish v3.1. I modified some of seam 2.2.1 snapshot of the source code, the hibernate validation replaced jsr303, remove the richfaces dependency, EJB3.0 replaced with EJB3.1.
I test on glassfish3.1 with:
hibernate 3.6 beta4, Mojarra jsf2.1 snapshot, primefaces2.2 rc1 snapshot.
But following error:
Caused by: java.lang.LinkageError: loader constraint violation: loader (instance of org/apache/felix/framework/ModuleImpl$ModuleClassLoader) previously initiated loading for a different type with name "javassist/bytecode/ClassFile"

So i change org.jboss.seam.util.ProxyFactory to javassist.util.proxy.ProxyFactory of javassist 3.12.0.GA and it work fine.
My question is what adverse effects will occur when i do the changing.
Have any suggestions?
