unable to make apache cxf and tika work within a custom connector

[matteogrolla]

Hi,
we are unable to make apache cxf and tika work within a custom connector.
We are launching the connector remotely and see that it never reaches fetch or prefetch methods. It dies during initialization, trying to initialize apache cxf

the source of the problem is probably
Caused by: javax.xml.bind.JAXBException: ClassCastException: attempting to cast jar:file:/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/jre/lib/rt.jar!/javax/xml/bind/JAXBContext.class to jar:file:/Users/matteogrolla/Development/alf_sourcesense/bancaditalia/connectors-sdk-resources/java-sdk/connectors/build/plugins/bdi-enterprise-search/lib/jakarta.xml.bind-api-2.3.2.jar!/javax/xml/bind/JAXBContext.class. Please make sure that you are specifying the proper ClassLoader.

here are the relevant excerpts from the logs
