Paul Sandoz updated WELDX-38:
-----------------------------
Attachment: jersey-gf-bundle.jar
I am observing a similar exception when attempting to use Weld integrated into GlassFish. I am not sure if the cause is exactly the same but it still might be useful information.
Glassfish's JAX-RS implementation, Jersey, needs to use a 299 Extension implementation such that the InjectionTarget of ProcessInjectTarget events can be adapted thus enabling JAX-RS artifacts to be injected.
If you copy the attached jersey-gf-bundle.jar into current nightly build of GF [1] to the location:
glassfish/modules/jersey-gf-bundle.jar
start GlassFish then deploy a simple 299 enabled web app you should see the following exception in the server.log when it attempts to create a client proxy to the Extension class:

A workaround is to add the following to the Import-Package header of the MANIFEST.MF:
javassist.util.proxy;resolution:=optional;version="3.8"
Note that this error only occurs for the Extension implementation class in the jersey-gf-bundle.jar and does not occur for other 299 managed beans declared in a web app.
Such a declaration should not be required as there is no direct dependency on that package. It is not clear to me if this is a class loading issue with Weld or a class loading issue with GlassFish's OSGi container, or a combination of both.
Unfortunately i cannot create a more isolated test case.

> Trying to mark a conversation as long-running causes an exception (java.lang.NoClassDefFoundError: javassist/util/proxy/ProxyObject) when the ServletConversationManager tries to get a proxy for the httpSession.
> The ProxyFactory.classLoaderProvider ends up resolving the classloader to an instance of org.apache.catalina.loader.StandardClassLoader (which doesn't know the javassist lib, since it's only in the app classloader).
