Dynamic AOP proxies for @Endpoints result in IllegalArgumentExceptions [SWS-366]

[gregturn]

Mark Diskin opened SWS-366 and commented

When using AspectJ advices on Endpoint classes will causes a "java.lang.IllegalArgumentException: object is not an instance of declaring class" exception.

See these forum posts for the stack and examples.

I am working on solving this, but as a workaround, you can use CGLIB-based proxies, rather than dynamic proxies.

I've decided not to fix this issue, because fixing it would break backwards compatibility with older releases.

So the workaround described earlier (using CGLIB proxies by specifying proxy-target-class="true" on the aop:aspectj-autoproxy or aop:config element) is the recommended fix.

I did change the exception thrown, so you now get a nice message, suggesting CGLIB, rather than the IllegalArgumentException thrown from deep in the JDK.
