 I'll take a stab at this for abcl-1.5.0 after I rewrite the Aether adapter
 to have more meaningful failures.

 Note that the naive implementation of dependency inclusions will not
 prevent incompatibilities between and within DEFSYSTEM forms, i.e. for a
 fragment like

 {{{
   (:mvn "net.sourceforge.owlapi/owlapi-distribution/4.2.6"
         :exclude (":log4j:1.2.14" ))
   (:mvn "org.apache/tomcat"
         :exclude (":log4j:1.2.13" ))
 }}}

 it is undefined which log4j will be picked up.

 It might be possible to do something intelligent with specialized class
 loaders, but given the impacts that Java 9 will have on locating and
 utilizing JVM artifacts, I'd rather do the simple implementation for
 exclusion to at least have some ability to get around bugs, and then
 revisit JVM artifacts when we have a reasonsable abstraction the combines
 Java [678] with Java 9.
