I upgraded our organization to 3.12.0.GA javassist and a lot of issues
went away. Still a few issues, and I think the guy who patched it for
us submitted that patch to javassist, but it's light-years less
problematic than 3.9.

After a jboss restart and clean deploy, the application is deployed
fine.
Below is what I did:
- javassist.jar is removed from JBOSS_HOME/server/default/lib
folder.
- javassist-3.9.0-GA.jar is put inside JBOSS_HOME/server/default/lib
folder.
- javassist-3.9.0-GA.jar is removed from WEB-INF/lib directory.
Thanks for your response.

I've been debuggin jboss now. During jboss startup,
javassist.util.proxy.ProxyFactory.setField() method throws the
exception in
the following highlighted line.
private void setField(String fieldName, Object value) {
if(thisClass != null && value != null)
try { Field f = thisClass.getField(fieldName);
SecurityActions.setAccessible(f, true);
*f.set(null, value);*
SecurityActions.setAccessible(f, false);
}
catch(Exception e) {
throw new RuntimeException(e);
}
}
*
Values Of setField() Parameters:*
value= instance of
"org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer"
fieldName="_method_filter"
In the highlighted line, JavassistLazyInitializer cannot be set to
null.
If I set a breakpoint to the highlighted line and set the
JavassistLazyInitializer instance to null, exception does not occur.

Changing javassist jar didn't work. I still receive the errors.
By the way, the exception is thrown by
"org.hibernate.tuple.entity.PojoEntityTuplizer".
Is there a incompatibility with the hibernate jars?
One more issue is that the logging level of the stack trace is in
WARN
level. And I still haven't encountered anything weird in runtime.

Hi,
I receive an error in my Tapestry webapp. I use Tapestry
5.1.0.5 and

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:

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...
