By the stack trace, it's evident that this use case was simply never
considered, the code could
be expanded to care for it as well (a bounding box without the coordinate
reference system
specification).
Looking at the (E)CQL parser code it seems to be possible to specify a CRS
for the bounding
box, I guess in that case a ReferencedEnvelope will be created, worth a
try: add a fifth parameter
in your BBOX filter, something like 'EPSG:4326', and see if that works.
My guess is that the store will work correctly only if the bbox is
specified in the data native
coordinate system.
