Of the JAX-RS implementations it seems RestEasy is the most difficult to get help for. If you look at the mailing list archive for the project at SourceForge you will notice almost none of the questions are answered or at least I have not seen one that was answered. On the JBoss community site there is very little discussion regarding the project.
Is it an unwanted child? I am starting to think it was a mistake choosing it as the JAX-RS implementation for our projects.
