[weld-issues] [JBoss JIRA] Created: (WELD-712) Regression in Extension proxy method invocations

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.Beta2 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.
