Several features install Stax2 API 4.2.0 and this breaks `woodstox-core-asl`, which tries to use a new incompatible version 4.2.0 with a different method signature. This module improve bundle import `org.codehaus.stax2.*` packages original version from "3.1.4" to range "[3.1.4,4)" and don't let `woodstox-core-asl` use the version 4+. It's needed deploy to repository and replace artifact in `org.apache.karaf.features.xml` config ```xml ``` Or update bundle with new location from karaf console ```bash update 354 mvn:org.codehaus.woodstox/woodstox-core-asl/4.4.1-ENTAXY ```
