The Metric and Operation annotations in the org.rhq.helpers.pluginAnnotations.agent package should use the LGPL license (the other annotations in the same package do so already).
Mattias Jiderhamn <mj-lists> made a comment on jira ISPN-2179 I am not sure about the conclusion here. The RHQ home page http://www.jboss.org/rhq clearly states that (the current version of) RHQ is licensed under GPL. Likewise the POM indicates GPL.
Tristan Tarrant <ttarrant> made a comment on jira ISPN-2179 Infinispan 5.2.0.Final does not depend on rhq-pluginAnnotations anymore.
