Your bundle requires "commons.net" version to be from 3.3-4 (exclusive) but AEM/Felix is unable to provide the same version. Hence, include "commons.net" bundle with either version from 3.3-4 and package it within your source code bundle. You may check if the same bundle is available in Felix with a different version or not?
Alternatively, if you don't need this bundle then add "!org.apache.commons.net.util" in the <Import-Package> of <maven-bundle-plugin>
Similar approach goes for "commons-validator". Provide either version from 1.6 to 2 or otherwise, block this dependency to be included in your import statements as applicable.
