Enums generated by JAXB include a fromValue method that converts an incoming value into the relevant constant. RestEasy is currently not compatible with JAXB generated enums, as it uses the valueOf method instead (which requires a string value that exactly matches the constant name).

Can a simple change be considerd (to org.jboss.resteasy.core.StringParameterUnmarshallerBinder) to support the JAXB generated fromValue method?

I've noticed that this problem has been fixed in CXF:
