Multiple instances of interceptors created for same target

XMLWordPrintable

      Using a Service class like this:

      @Interceptors(MyInterceptor.class)
public class TestService {
...
}

@ManagedBean
public class MyInterceptor {
Object field;
@AroundConstruct
    public void wrapConstructor(InvocationContext ctx) throws Exception {
         field = new Object();
}
 @AroundInvoke
    public Object guard(final InvocationContext context) throws Exception {
        assert field != null;
}
}

      I would expect the assert to pass. However it fails, because weld creates two instances of this interceptor, one for each Interception Type.

      I did not see this documented, and I am not sure if it is a bug. If not, more documentation would help.

      JSR 318 seems to say this:
      http://download.oracle.com/otndocs/jcp/interceptors-1_2-mrel2-spec/
      "Except as noted below, when the target instance is created, a corresponding interceptor instance is created for each associated interceptor class."

      "The applicability of a method-level interceptor to more than one method of an associated target class does not affect the relationship between the interceptor instance and the target class—only a single instance of the interceptor class is created per target class instance"

            For the record - it does not work for interceptors that are CDI beans either. Although the interceptor spec is not entirely clear, the team agreed that it should be fixed.

            This was java version "1.8.0_77" on Ubuntu 15.10.
            I could reproduce with tests running org.jglue.cdi-unit:cdi-unit:3.1.3, which in turn uses org.jboss.weld.se:weld-se-core:jar:2.2.13

            Hi tkruse_jira, thanks for noticing. It looks like a bug. What environment do you use? Also I would expect this will work for interceptors that are CDI beans (i.e. using @Interceptor and interceptor bindings).
