Andreas Veithen commented on AXIS2-4902:
----------------------------------------

Short status update on this issue: I think that the proper long term solution 
is to make sure that Axis2 has no direct dependencies on the classes in 
axiom-impl (but only on axiom-api). Basically, at the Maven level, axiom-impl 
should become a dependency with scope 'runtime' instead of 'compile'. I see 
this as part of a larger effort to make sure that Axiom has appropriate and 
well defined public APIs for all the features needed by Axis2 (see e.g. 
AXIOM-313). I already did some modifications and cleanups, but this will take 
some time to complete.

>             Project: Axis2
>          Issue Type: Bug
>    Affects Versions: 1.5.3, 1.5.2

> The problem:
> * In Axis2 1.5.2, we upgraded Axiom to 1.2.9, and Axis2 1.5.3 uses Axiom 
> 1.2.10.
> * In r741656, David Illsley changed the way Axiom is OSGi-ified. In 
> particular the axiom-impl bundle now has Private-Package: org.apache.axiom.*. 
> This is of course entirely correct because other bundles should only depend 
> on the Axiom API, not on classes of a particular implementation.
> * The Axis2 OSGi bundle has Import-Package: org.apache.axiom.om.impl.llom. 
> The reason is that there is indeed code in Axis2 that depends directly on the 
> LLOM implementation classes. This should of course not be the case, but 
> that's the way it is for the moment.
> * There are no unit tests for the Axis2 OSGi bundle.
> Result: In Axis2 1.5.2, the OSGi bundle is broken because of the upgrade to 
> Axiom 1.2.9. It is expected that this issue also affects the current trunk.
> Steps to reproduce (with Axis2 1.5.3):
> 1. Download, extract and start the Felix Framework Distribution.
> 2. Install the following bundles:
> install 
> http://repo1.maven.org/maven2/org/apache/ws/commons/axiom/axiom-api/1.2.10/axiom-api-1.2.10.jar
> install 
> http://repo1.maven.org/maven2/org/apache/ws/commons/axiom/axiom-impl/1.2.10/axiom-impl-1.2.10.jar
> install http://apache.megamobile.be//felix/org.apache.felix.scr-1.6.0.jar    
> install 
> http://repo1.maven.org/maven2/org/apache/axis2/org.apache.axis2.osgi/1.5.3/org.apache.axis2.osgi-1.5.3.jar
> install 
> http://repo2.maven.org/maven2/org/apache/servicemix/bundles/org.apache.servicemix.bundles.wsdl4j/1.6.2_3/org.apache.servicemix.bundles.wsdl4j-1.6.2_3.jar
> install 
> http://repo2.maven.org/maven2/org/apache/geronimo/specs/geronimo-activation_1.1_spec/1.1/geronimo-activation_1.1_spec-1.1.jar

> install 
> http://repo2.maven.org/maven2/org/apache/geronimo/specs/geronimo-servlet_2.5_spec/1.2/geronimo-servlet_2.5_spec-1.2.jar
> install 
> http://repo2.maven.org/maven2/org/apache/geronimo/specs/geronimo-stax-api_1.0_spec/1.0.1/geronimo-stax-api_1.0_spec-1.0.1.jar

> http://repository.springsource.com/maven/bundles/external/org/apache/commons/com.springsource.org.apache.commons.logging/1.1.1/com.springsource.org.apache.commons.logging-1.1.1.jar
> 3. Attempt to start the Axis2 bundle.
> This results in the following error:
> org.osgi.framework.BundleException: Unresolved constraint in bundle 
> org.apache.axis2.osgi [8]: Unable to resolve 8.0: missing requirement [8.0] 
> package; (package=org.apache.axiom.om.impl.llom)
