That answers your question. However, the CDI EG kind of anticipated problems with legacy extensions not using the SPI properly and added the following statement: "The container is permitted to define a non-portable mode in which getBeans(String) may be called from an observer of the AfterBeanDiscovery event." The non-portable mode is not in Weld yet but will be since 2.0.2.Final. The easiest thing you can do is to repackage solder and disable the org.jboss.solder.exception.control.extension.CatchExtension extension (assuming you use Solder for other parts than Catch). Jozef
