Could not find artifact com.sun.xml.bind:jaxb-impl:jaxb1-impl.jar:2.2.3-1 in central (http://repo1.maven.org/maven2/)

this artifact does not exist and is computed from the META-INF/MANIFEST.MF Class-Path key of the file com/sun/xml/bind/jaxb-impl/2.2.3-1/jaxb-impl-2.2.3-1.jar
We may override some method in the Classloader we use to avoid looking for Class-Path dependencies as all the dependencies shall be provided to the classloader itself from the pom resolved dependencies.
