Re: [aspectj-users] aspects in annotations

Eric,

I have opened https://bugs.eclipse.org/bugs/show_bug.cgi?id=122742. This is not specifically a load-time weaving problem but one of an @AspectJ aspect advising itself. The workaround is to define the aspect separately as in your first post.

Hi,

When I uses the following command to run, it fails with java.lang.VerifyError (class: A, method: stop signature: ()V) catch_type not a subclass of Throwable


   java -classpath aspectjweaver.jar:. -javaagent:aspectjweaver.jar A


And the output is

info AspectJ Weaver Version DEVELOPMENT built on Thursday Dec 22, 2005 at 11:22:16 GMT

I am using SUN JDK (build 1.5.0_06-b05).


Thanks,

Eric,

Can I assume the code below for "A.java" is generated? When I try to compile it as show with javac I get errors:

Ap.java:6: unclosed string literal
@AfterThrowing (pointcut = "(execution(public void A.start() throws
                           ^
Ap.java:8: unclosed string literal
java.lang.Exception))", throwing = "ex")
                                     ^
Ap.java:20: ')' expected
}
^
3 errors

If however the "@AfterThrowing" annotation is on a single line your program seems to work:
