Subject [jira] Commented: (WINK-229) JAXBXmlProvider should tolerate user jaxb contexts
Date Fri, 06 Nov 2009 23:48:32 GMT


Bryant Luk commented on WINK-229:

I originally got a repeatable problem in my build environment but after adding:

    public String getPropertiesFile() {
        return "META-INF/";

to the JettisonJAXBContextResolverTest, the test passed for me (JDK 1.6 this time).  If the
Jettison provider is auto-registered via wink-application, the reader is disabled.  The
file disables the auto-registration allowing you to turn on the Jettison provider as a reader
before registration.  The reason the reader is disabled by default is because of a bug in
Jettison where malformed JSON may cause infinite loops.

> Ran into a sample that had an extra creator method in the ObjectFactory that returned
a JAXBElement.  When this method exists, and the jaxbcontext is created using the String signature
in a user's JAXB context resolver, the unmarshaller will call the ObjectFactory method that
returns the JAXBElement, and thus the provider will return a JAXBElement, which may not be
the desired object for the resource -- this would result in an IllegalArgumentException: argument
type mismatch when calling the resource method.
> See patch, with test.  It'll make sense.
> Also, we don't have a good set of tests for the JAXBXmlProvider.  The one included here
in the patch is a good one to use for additional JAXB tests.
