LinkageError starting server with CXF

[Cristiano Ghersi <cr...@abodata.com>]

Hello,

 

I'm facing up with a strange issue.

I'm using CXF under OSGI (Equinox), using the single bundle lib
(cxf-dosgi-ri-singlebundle-distribution-1.2).

I imported it into Eclipse Galileo RCP (under Windows Vista), and now it is
a plug-in project exactly as my other bundles.

 

When I start my osgi from Eclipse, all the bundles using CXF results in the
following error:

Exception in thread "CXFServerThread" java.lang.LinkageError: loader
constraint violation in interface itable initialization: when resolving
method
"org.springframework.beans.factory.support.AbstractBeanFactory.getParentBean

org/springframework/beans/factory/support/AbstractBeanFactory, and the class

org/springframework/beans/factory/HierarchicalBeanFactory have different

Obviously this error precludes the correct behavior of my application,
although all the bundles seems running (state ACTIVE).

 

The unbelievable thing is that if I open the MANIFEST.MF file of the
cxf-dosgi-ri-singlebundle-distribution-1.2 bundle and "touch" it (e.g.
adding a space at the end of a line in the middle of the file), at the next
start of my app, all runs perfectly.

If I restart my app, the previous error occurs.

So I need to touch the MANIFEST.MF file every time I restart my app in order
to make it run.

 

Any hint about this behavior?

 

Thank you very much!

Best regards
