org.jboss.resteasy.logging.Logger uses TCCL to load logging implementation

Description of problem:
Resteasy should use its own classloader to load classes.

Example scenario where this is a problem:
Login module depends on resteasy. When login module is invoked, the TCCL is set to the deployment's CL, which does not depend on resteasy. This causes a CNFE in org.jboss.resteasy.logging.Logger.setLoggerType()
