GoogleCodeExporter commented 8 years ago 
I am quite not sure if I really fixed this bug. From my point of view it could 
happen that the default thematic grids are requested and the PersistenceService 
is not initialized with an input-stream to the default grids yet. There was a 
missing null check, so that XStream was asked to load the grids from a 
null-stream.
