Although the method info.magnolia.cms.core.Path$getUniqueLabel(Node, String) is deprecated it still uses the artifact JUG in order to generate random UUIDs.
This is not necessary as the required functionality is part of the JRE since 1.5 and has been removed in my local git. The following commit modifies the method and removes the artifact:

The artifact has only been removed in core so it still might be used in other magnolia projects although a java comment suggests otherwise.
