Why JoinPoint interface present in both aspectjrt and aspectj-weaver?

Some parts of this message have been removed. Learn more about Nabble's security policy.

Hi,

 

I am currently migrating my application to OSGi environment. I am getting linkage error while classloader is trying to load the class JoinPoint.

 

Caused by: java.lang.LinkageError: loader constraints violated when linking org/aspectj/lang/JoinPoint class

 

I find that both aspectj-weaver and aspectj-runtime have this interface defined. Is there any specific reason why this interface is included in both the jars?

 

Regards,

Shashi

Hi Andy/Tahir,

Thanks for your replies.

I had downloaded the bundles from springsource. However I was importing both the bundles in one of my application bundles. This caused a problem. As soon as I remove the weaver bundle from the dependency list the problem is resolved as expected.

However the basic problem remains i.e. if I have to use both the bundles together it wouldn't work since the package of the same version is exported by both the bundles.

Thanks,
Shashi

As Tahir suggests, the jars are supersets of each other. aspectjrt.jar
is the smallest, aspectjweaver is next and aspectjtools after that.
The manifests packaged with each are not really suitable for direct
deployment into an OSGi environment.  I believe the versions hosted in
the SpringSource bundle repo have the correct manifests, see
http://www.springsource.com/repository/app/library/version/detail?name=org.aspectj&version=1.6.5.RELEASE&searchType=librariesByName&searchQuery=aspectj
