Hi John, I've checked the bytecode of the generated proxy (http://docs.jboss.org/weld/reference/latest/en-US/html/configure.html#_debugging_generated_bytecode) and found out that the only ignored methods were getProperty() and setProperty() and then I realized this is a duplicate issue - see also WELD-2255. The problem with Groovy and proxies is fixed in Weld 2.4.1 (I've tried to upgrade hammock and CXFTest is passing now).
