As far as I understand, project examples plugin (at least in JBT) points to some xmls where are project examples defined (name, description, location).
Project examples plugin from JBT 4.1.2.CR1 (org.jboss.tools.community.project.examples_1.5.4.Final-v20140303-0549-B152.jar) points to http://download.jboss.org/jbosstools/examples/project-examples-maven-4.1.1.GA.xml and this file points all its examples to directory 4.0.0.GA (http://download.jboss.org/jbosstools/examples/4.0.0.GA/) even though there are newer versions in directory 4.1.1.GA (http://download.jboss.org/jbosstools/examples/4.1.1.GA/).

I think this issue also affects 4.1.1 (and maybe 4.1.0), but I anly tested it now on 4.1.2.CR1.
