When declaring a dependency in a pom.xml with the type EJB and then resolving it into a MavenResolvedArtifact the method getCoordinate().getPackagingType() returns PackagingType.JAR instead of PackagingType.EJB. So it seems like it sets the PackagingType to the extension of the resolved file. It works fine when a dependency has type war, since type and extension is the same.
