Hi Every one,  
We are having a legacy application which was running fine with following  
Weblogic 12.1.3.0  
Hibernate 3.5  
Java7  
Now with a compulsary upgrade of weblogic and Java to  
Weblogic 12.2.1.4  
Java8  
HIbernate 3.5 (we cannot upgrade this now as it will increase the complexity)

we are getting below exception. There is no change in any config file only change is with Weblogic and Java version.

Does this implies that there is some compatibility issue between hibernate, weblogic and java? Or there is some other things missing?  
I have already tried adding javassist.jar in our war file, but it did not work.
