Summary

0002344: WebBeans @Interceptor integration

Description

(rep by wesley)
I wrote an interceptor for some webbeans component.

code:
==============The InterceptorBindingType============
@InterceptorBindingType
@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
public @interface BlockCachable {
}
============The Interceptor=============
@BlockCachable
@Interceptor
public class BlockModelCacheInterceptor {
private static final Log log =
LogFactory.getLog(BlockModelCacheInterceptor.class);
public BlockModelCacheInterceptor() {
}
@AroundInvoke
@SuppressWarnings(value = "unchecked")
public Object invoke(final InvocationContext invocation) throws Throwable {
  log.info("intercepted");
  return invocation.getTarget();
}
}
=======The component should be intercepted========
@Component
public class MyBean{
@BlockCachable
public void execute() {
  // do something
}
}
============================================
Note: all interceptors were registed in web-beans.xml.

When starting Resin, resin produce exceptions.

================================================================
I've examined the source code of
com.caucho.webbeans.bytecode.InterceptorGenerator, and found
strange code below:

174: if (true) {
175: out = Vfs.lookup("file:/tmp/caucho/qa/temp.class").openWrite();
176: out.write(buffer, 0, buffer.length);
177: out.close();
178: }

It seems InterceptorGenerator will definitely execute line 175 and produce
an exception, if any interceptors need to
be initialized.

I modified above lines as below

174: if (false) {
175: out = Vfs.lookup("file:/tmp/caucho/qa/temp.class").openWrite();
176: out.write(buffer, 0, buffer.length);
177: out.close();
178: }

and everything goes fine.

Should this be a bug or something need extra config to go?
