The problem is this:
processor.configure("template processor", new HashMap<String, Object>());
return processor.getVirtualSize(file);
It confitures the processor with a empty HashMap, but the check in the
processor is:
public boolean configure(String name, Map<String, Object> params) throws
ConfigurationException {
_storage = (StorageLayer)params.get(StorageLayer.InstanceConfigKey);
if (_storage == null) {
throw new ConfigurationException("Unable to get storage
implementation");
}
Since the HashMap is empty null is returned and this exception is thrown.
No need to configure the Processor as far as I can see.
