Hi Michael, could you please open a new issue in jira about this.
Having said that I don't see a solution to fix this if you use constructors of Marshaller yourself. The prefered way to construct a marshaller instance is through XMLContext.createMarshaller(). But using XMLContext wouldn't help you either at the moment as there seams to be a bug that always reloads properies even if it gets reassigned to the ones loaded at construction of XMLContext directly thereafter.
