Here is the relevant error: java.lang.ClassNotFoundException: edu.emory.mathcs.backport.java.util.concurrent.BlockingQueue
libbackport-util-concurrent-java is in the process of being removed in Jessie (there are 3 rdeps left). backport-util-concurrent.jar has been removed from the classpath set my maven-ant-helper, that may explain the issue.
