This artifact provides a single jar that contains all classes required to use remote EJB and JMS, including
all dependencies. It is intended for use by those not using maven, maven users should just import the EJB and
JMS BOM's instead (shaded JAR's cause lots of problems with maven, as it is very easy to inadvertently end up
with different versions on classes on the class path).

*
* Definition of an interface for components that can perform introspection on

*
* Before {@link PropertyUtils} can be used for interaction with a specific Java
* class, the class's properties have to be determined. This is called
* introspection and is initiated automatically on demand.
* PropertyUtils does not perform introspection on its own, but
* delegates this task to one or more objects implementing this interface. This
* makes it possible to customize introspection which may be useful for certain
* code bases using non-standard conventions for accessing properties.
