HeaderParam labels in CXF-2.1.2 REST seem to be case sensitive. The
problem appears only when using Tomcat-6.0.18 through its AJP connector.
It does not appear when Tomcat is accessed through its HTTP connector.
mod_jk (1.2.26) is passing headers unmodified to AJP, so differences in
AJP & HTTP connectors make this issue manifest.
The following patch fixed the bug for us. Please have a look and comment:
