resolve potential LinkageError
------------------------------

                 Key: WBRI-193
                 URL: https://jira.jboss.org/jira/browse/WBRI-193
             Project: Web Beans
          Issue Type: Patch
    Affects Versions: 1.0.0.BETA1
            Reporter: Takeshi Kondo
            Priority: Trivial


Some time age, LinkageError is caused by Seam's Javassist ProxyFactory usage.
It same applies to WebBeans.

if possible, make a modification 

from 
---
	     ProxyFactory proxyFactory = new ProxyFactory();
         proxyFactory.setSuperclass(getSuperClass();
         proxyFactory.setInterfaces(getInterfaces());
         return proxyFactory;

to 
---
	 ProxyFactory proxyFactory = new ProxyFactory();
         Class<?> superClass = getSuperClass();
         if(superClass != Object.class)
         {
            proxyFactory.setSuperclass(superClass);
         }
         proxyFactory.setInterfaces(getInterfaces());
         return proxyFactory;

---

Apply to this patch, 
If proxy target class is interface, generated proxy class name changes 
form "org.javassist.tmp.java.lang.Object_$$_javassist_0"
to "org.javassist.tmp.java.util.List_$$_javassist_0".

All interface generated proxy class name is "org.javassist.tmp.java.lang.Object_$$_javassist_(number)"

Because proxy class name pattern is monotone,
duplicate proxy class name, then it causes LinkageError.
