I think you should update the javassist in jboss/server/default/lib/ folder.

Hi,
I receive an error in my Tapestry webapp. I use Tapestry 5.1.0.5 and Jboss
4.2.3-GA.
*Scenario 1:*
My web application contains javassist 3.9.0.GA in WEB-INF/lib folder. And
there is also another javassist.jar(3.6.0.GA) file inside
jboss/server/default/lib folder.
During deployment of the web application, I receive such an exception:
22:12:28,373 WARN buildProxyFactory

This error doesn't prevent deployment. And I have no idea what the impact of
this error is or will be. I can select, and insert via webapp.
*Scenario 2:*
If I exclude javassist 3.9.0.GA from my Tapestry webapp and leave jboss's
javassist.jar in place, the application deploys without exception. But, in
this case, I encounter an exception in runtime:
org.apache.tapestry5.internal.services.TransformationException:
javassist.CannotCompileException: broken method
InternalClassTransformation[
public com.mycompany.webapp.pages.PasswordHint extends
com.mycompany.webapp.pages.BasePage
add method: private void _$write_logger_2(org.slf4j.Logger $1)
throw new java.lang.RuntimeException("Field
com.mycompany.webapp.pages.PasswordHint.logger is read-only.");
replace write logger: _$write_logger_2();
..........
I am now following scenario 1, and I have not faced anything weird in
runtime? Any suggestions are appreciated:),
Thanks...
