+ * Thread.currentThread().getContextClassLoader() but during initialisation it loads the classloader which means
+ * this classloader will never pickup the plugin classes.
+ *
+ * With this loader we can add jars we load during the plugin loading and the jsp will pick it up because this is
+ * the same classloader.
