Strange JAXB exception when serializing a bunch of model IDs in ALS:

Villu notes that this can be resolved by using MOXy instead of the default JAXB. impl More on this to come.

With this change, you can enable MOXy to work around this with -Djavax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory
