Description

We have a tool that loads libraries for our plugins at runtime. Jackrabbit-Standalone is loaded and is needed to connect to Adobe Experience Manager. However, when I try to run the rule I get
Exception in thread "Thread-3" java.lang.NoClassDefFoundError: org/apache/jackrabbit/commons/JcrUtils

If I add JackRabbit-Standalone to the classpath before hand I do not get this error. We have loaded hundreds of jars using our plugin loader and this is the first time I have experienced something like this.
