We are running into an odd situation involving the FeatureDatasetFactoryManager
and aggregate ncml datasets relevant to the NetcdfFileCache. With the cache
active, subsequent attempts to get an aggregate ncml wrapped by a
FeatureDataset results in the factory manager being unable to properly
determine the factory for the aggregation.
We receive the following error on subsequent attempts to load the aggregation
from the FeatureDatasetFactoryManager:
Table TopScalars/PsuedoStructure(time) featureType Station: lat/lon/time coord
not found
**Failed to find FeatureDatasetFactory for= wqbawagg datatype=STATION
(we also get the same error for datatype=ANY_POINT; the aggregation being used
is a time series).
I confirmed with OPENDAP that the coordinates are in the dataset, and as I said
that the first time loading the aggregation is successful; just the subsequent
attempts to load it fail.
Here is the example aggregation that was tested with (use SOS access to see the
exception returned, it is a custom message - not what the manager returns):

Turning off the NetcdfFileCache solves the issue, however, we would prefer to
work with the cache on (having it completely off isn't really an option) .
Any help with this would be greatly appreciated.
