Pete Muir updated WELD-712:
---------------------------
Fix Version/s: 1.1.0.CR1
(was: 1.1.0.Beta2)
> Regression in Extension proxy method invocations
> ------------------------------------------------
>
> Key: WELD-712
> URL: https://jira.jboss.org/browse/WELD-712
> Project: Weld
> Issue Type: Bug
> Components: Proxies, Reflection layer
> Affects Versions: 1.1.0.Beta1
> Environment: Latest GlassFish that has 1.1.0-01-glassfish build of
> Weld integrated. To reproduce the problem the following system property needs
> to be set to bypass the Jersey workaround for this issue.
>
> <jvm-options>-Dcom.sun.jersey.server.impl.cdi.lookupExtensionInBeanManager=true</jvm-options>
> Reporter: Sivakumar Thyagarajan
> Fix For: 1.1.0.CR1

> Glassfish issue 13131 [1], involving the Jersey portable extension, notes
> that there has been a regression in the last integration of Weld
> (1.1.0-01-glassfish).
> It appears that invocations on observer methods of container lifecycle events
> are handled in the proxy and delegated to the proxied instance of the
> Extension, whereas invocations of non-observer methods on a Extension that is
> obtained from BeanManager, are directed towards the non-proxied instance of
> the Extension. This behaviour appears to have been changed after Weld 1.0
> More details:
> The Jersey extension has a private initialization method (initialize() [2])
> that inits the state of the extension during beforeBeanDiscovery. I notice
> that there are two instances of the Extension being created (because the
> extension is being proxied) -- let us call it actual_instance1 and
> proxy_instance_2.
> beforeBeanDiscovery observer method is called on proxy_instance_2 and this
> method call in turn delegates to actual_instance1 and initialize() method is
> called on actual_instance1. So now actual_instance1's state is initialized
> correctly.
> However later when the Extension is looked up through the BeanManager
> elsewhere [3], the proxy_instance_2 is returned. When a non-observer method
> (lateInitialize [4]) is called on this instance proxy_instance_2, this method
> call goes to proxy_instance_2 and is not forwarded to actual_instance_1.
> Since the state is not initialized in proxy_instance_2, this call fails.
> Please see the attached text file for stack traces related to the various
> stages discussed above and also contact me should you need to reproduce this.
