AspectJ LTW on Virgo 3.6.2 [message #1067659]

I am trying to get AspectJ LTW working on Virgo (3.6.2.RELEASE on JRE 1.6.0_37). The aspect and classes to weave are contained in the same bundle. Other topics in the forum suggest that getting this working is as simple as setting <context:load-time-weaver aspectj-weaving="on"/> or configuring Virgo to run with the equinox weaving hooks when weaving aspects contained in a different bundle. I have tried various combinations with no luck.
I attach a simple project which works properly when run as a JUnit test but when I deploy it as a bundle I get the "Found load-time weaver bean for bundle ... Switching to ServerLoadTimeWeaver" but the aspect is not called.
What am I doing wrong?

Hi Rigas,

I changed your maven-bundle-plugin configuration to

				<configuration>
					<instructions>
						<Bundle-Blueprint>OSGI-INF/blueprint/blueprint.xml</Bundle-Blueprint>
						<Import-Library>
							org.springframework.spring
						</Import-Library>
						<Import-Package>
							!org.osgi.service.blueprint,
							org.aspectj.lang,
							*
						</Import-Package>
						<Export-Package>org.aaaa</Export-Package>
					</instructions>
				</configuration>

and simplyfied the consumer

	@PostConstruct
	protected void start() {
		LOG.info(this.getClass().getSimpleName() + ".start()");
		service.sayHello("Rigas");
	}

and your Aspect is called:

INFO  region-dm-1 org.aaaa.impl.HelloWorldServiceConsumerImpl                       HelloWorldServiceConsumerImpl.start()
ERROR region-dm-1 System.err    [KernelBundleClassLoader@492396a8] debug weaving 'org.aaaa.impl.Aspects'
INFO  region-dm-1 org.aaaa.impl.Aspects                                             sayHello called
INFO  region-dm-1 org.aaaa.impl.HelloWorldServiceImpl                               sayHello: Rigas

Hope this helps,
florian
