[jboss-jira] [JBoss JIRA] Commented: (JBAOP-731) problem with javac->aopc->javac sequence

[Andrew Dinn (JIRA)]

    [ https://jira.jboss.org/browse/JBAOP-731?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12541506#action_12541506 ] 

Andrew Dinn commented on JBAOP-731:
-----------------------------------

One thing you might try as a workaround is to compile the subclass against the superclass bytecode as it was before applying the AOP transform (assuming that this is an option for you and/or anyone consuming your code). The resulting bytecode for the subclass should still be able to be loaded into the target runtime alongside the AOP-transformed version of the superclass.

> I'm trying to switch from JBossAOP 1.5.6 to 2.1.1 and can't build my project, looks like there are some problems with aop-compiled classes. Here's what happens: first we build our interface classes, let's say there's *abstract* POJO1 among them. Then we run AopC on them, and it modifies POJO1.class
> Then we compile some more classes, and there's non-abstract POJO2 there, which extends POJO1. At this time javac fails with this message:
> POJO2 is not abstract and does not override abstract method _getAdvisor() in org.jboss.aop.Advised
> javap shows that POJO1 now implements Advisable and indeed contains _getAdvisor() method, but this method is not abstract! I'm confused.
> Running AopC after compiling all of the classes works fine. Making POJO1 non-abstract also makes javac happy.
> I'm attaching a testcase. Unpack it into jboss-aop-2.1.1.GA/docs/aspect-framework/examples/bug and run ant there to reproduce the problem.
