activemq-all-5.8.0.jar and older versions do not contain any .java files, only .class files as I would expect. Strating in version activemq-all-5.9.0.jar .java and .class files are included in the JAR.
Was this intentional? I'm having a problem related to the fact that Maven is attempting to compile your .java files. I admit that I'm surprised that Maven is attempting to compile code inside your JAR, and that may be a problem. However, it seems odd to me that the .java files are included in the .jar file, normally they would only appear in the sources jar (example: activemq-all-5.9.0-sources.jar).
