Description

Hello,

Please help to find solution for dependicy conflict.

I have installed on karaf, next features:

• camel-cxf » 3.8
• camel-core » 3.8
• apache-cxf » 3.4.2

When i try to use JAXWS to publish servlet, i got exception:

 

java.lang.NoSuchMethodError: org.codehaus.stax2.ri.EmptyIterator.getInstance()Lorg/codehaus/stax2/ri/EmptyIterator;

 

 

After some investigation, i found next dependicies:

1. Camel CXF

camel-cxf » 3.8 -> cxf-rt-frontend-jaxws » 3.4.2 -> Apache CXF Core » 3.4.2 -> Woodstox » 6.2.3

As i undertand  - woodstox-core renamed, and named woodstox-core-asl in the past.

 

2. Camel Core 

It use xml-specs-api feature, that have bundle:

    <bundle>mvn:org.codehaus.woodstox/woodstox-core-asl/4.4.1</bundle>

Wich is the old fashion of woodstox-core.

 

If i manually uninstall bundle mvn:org.codehaus.woodstox/woodstox-core-asl/4.4.1 from karaf, everything works. I can't force my bundle, to take new woodstox-core instead old woodstox-core-asl...

I think the problem is because this is not a different versions, it is a artifact rename, and classloader take first jar (woodstox-core-asl) and use it's classes.
