Yea. That will definitely cause an issue on AppEngine. My suggestion would
be to change all the calls in setProviders(Object... providers) to be wrapped
with an exception catch that would log that it wasn't registered:
if (MessageBodyReader.class.isAssignableFrom(oClass)) {
try {
messageReaders.add(new
ProviderInfo<MessageBodyReader>((MessageBodyReader)o));
}catch (Throwable t) {
//could not register it
}
}
Also, change the calls in the static initializer to be more like the
JSONProvider which is then not loaded if the requirements for the
JSONProvider are not met.
