ModuleClassLoader breaks Aspect-J non-load-time-weaving aspects ---------------------------------------------------------------- Key: AS7-6305 URL: https://issues.jboss.org/browse/AS7-6305 Project: Application Server 7 Issue Type: Bug Components: Class Loading, Web Affects Versions: 7.1.1.Final, 7.2.0.Alpha1 Environment: Windows 7 Reporter: jarkko rantavuori Assignee: David Lloyd Attachments: MyMethodTrace.java, MyMethodTraceAspect.java, spring-app-aop-datasource-1.0.0-BUILD-SNAPSHOT.war, spring-mvc-aop-datasource-app.zip Special measures need to be taken for load-time-weaving with aspects, but using them without load-time weaving works normally OOB. However, if this kind of Spring configuration is used: <!-- Test to get a data source --> <jee:jndi-lookup id="dataSource" jndi-name="jboss/datasources/ExampleDS"/> <!-- AOP part --> <bean id="methodTraceAspect" class="fi.eis.applications.jboss.poc.gemini.spring.aop.support.api.MyMethodTraceAspect"/> <aop:aspectj-autoproxy /> <!-- end AOP --> <bean class="fi.eis.applications.controllers.HomeController"> <constructor-arg ref="dataSource" /> </bean> JBoss tries to use methodTraceAspect also on the data source. Data source is loaded by ModuleClassLoader that in has only visibility to org.jboss.jca.adapters* classes (confirmed with a debugger), so it cannot find the aspect class anymore, making aspect-j throw org.aspectj.weaver.reflect.ReflectionWorld$ReflectionWorldException: warning can't determine implemented interfaces of missing type fi.eis.applications.jboss.poc.gemini.spring.aop.support.api.MyMethodTraceAspect [Xlint:cantFindType]. This has large problems in bigger applications, where general AOP pointcuts are used - no jboss-module stuff can be used as beans, anywhere. I'm aware of no workaround for this.
