Maven Plugins and Stack Overflow Assemblies

I have a fairly simple RESTEasy client application that I tried to compile into a standalone JAR file using both the Maven Shade and Assembly plugins. Maven will successfully package the application and it will start normally, but in the end I get the following error:

The call stack after org.jboss.resteasy.client.core.BaseClientResponse.readFrom (BaseClientResponse.javahaps84) is repeated again and again until the memory is exhausted.

My code is not a problem. An application works fine when it is packaged using the Maven dependency plugin .

My code relies on groups called regex (which rely on Java 1.7), but I can confirm that Maven and the application itself are compiled and executed using the correct JDK.
