I've noticed that when using CXF as a Maven dependency and aggregating it into an uber-Jar using the Maven Shade plugin there is an issue in that by default, the META-INF/cxf/bus-extensions.txt file (and other necessary CXF resources) aren't aggregated properly and loaded properly. They are kept in separate files. For examples of this, see:
The fix is to use the Maven Shade Plugin's AppendingTransformer to combine all the copies of the bus-extensions.txt file present in the jars. See these examples here:
You can handle it with the plugin configuration for the Shade plugin e.g., like this:
