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).

The newest version!

/**
 * Bundler which doesn't bundle :-) Can be used to measure the diff between bundling and non-bundling (e.g. at runtime)
 * This bundler doesn't use a pool of buffers, but creates a new buffer every time a message is sent.
