[undertow-dev] ClassCastException when retrieving a beans from CDI with Weld Proxy beans

I posted this problem on StackOverflow, but after doing more research, I'm not sure if this is a Weld, JBoss/WildFly or undertow issue. Or whether its a framework issue, or how the framework is being used. If this is not the correct list, can you please let me know which list/group I should be directing the issue to? I'm running into a strange problem and error message that I do not understand. I'm running my application on JBoss 7 EAP. Caused by: java.lang.ClassCastException: Cannot cast ejbs.LoginManager$417755913$Proxy$_$$_Weld$EnterpriseProxy$ to ejbs.LoginManager I'm trying to programatically retrieve an EJB from the CDI context by using its interface and am getting this error message. I've created a sample proof-of-concept that is trying to retrieve EJB beans from the CDI context public <T> T getSesionBean(Class<T> clazz, String name) { Properties properties = new Properties(); try { InitialContext initContext = new InitialContext(); return clazz.cast(CDI.current().select(clazz).get()); } catch (Exception e) { // TODO Auto-generated catch block throw new RuntimeException(e); }} It is being called as: LoginManager login = getSesionBean(LoginManager.class); with my EJB defined as: @Stateless(name=&quot;LoginManager&quot;)@Local(LoginManager.class)(a)LocalBinding(jndiBinding=&quot;LoginManager&quot;)public class LoginManagerBean implements LoginManager {.........} I don't understand it. I'm expecting the bean being retrieved from the context to be a proxy. Shouldn't it be castable to my interface? Otherwise, how am I supposed to retrieve it? More interestingly, this does not seem to be a consistent error; sometimes the code works fine. Sometimes it fails. I haven't been able to determine what makes it work or throw an exception. I found a related issue here <https://issues.jboss.org/browse/WELD-1498>;, but not sure if this is the same problem and/or which version of Weld is used in JB7EAP. I'm including the following dependency in my application: <dependency> <groupId>org.wildfly</groupId> <artifactId>wildfly-ejb-client-bom</artifactId> <version>10.1.0.Final</version> <type>pom</type> </dependency> Am I doing something completely wrong? If this is a Weld bug, can I use a different proxy system than Weld? Is this even configurable in undertow? Thanks, Eric
