Should CacheStaticMethodMatcherPointcut be Serializable?

[Darius]

On our installation, we're getting a non-serializable error on the
class CacheStaticMethodMatcherPointcut.
Merely to confirm, I modified the source of the class and marked its
only field transient, and the error went away.

Should that class be Serializable, or should I be looking for
something else (e.g. to figure out why it is being added to the
session -- and then serialized -- in the first place)

Thanks for any help with this

[Eric Dalquist]

Could you post the stack trace of the error? We haven't seen that but we may not be testing your use case and if that class (and its members) need to be serializable we can easily make that change.

Thanks for the reply. Here's the stacktrace:

[Eric Dalquist]

Hrm, I guess that isn't as interesting as it just shows Tomcat's shutdown thread saving the session. You are right, the bigger question is how CacheStaticMethodMatcherPointcut ended up in your servlet session.

CacheStaticMethodMatcherPointcut is auto-registered as a bean in the Spring application context when the <ehcache:annotation-driven> element is present. The only other piece of our code that references it is the DefaultBeanFactoryPointcutAdvisor which returns the pointcut to use for evaluating which bean methods should have caching advice applied.

Are you referencing your spring app-context from an object stored in the session?

-Eric

[Darius]

Basically, one of the classes being serialized had one object that was
being @Inject-ed into it by Spring. Some of the methods on this
injected object had Ehcache Spring Annotations. It was failing while
trying to serialize.
