Requesting null instrument response

There are some channels that have timeseries data but do not include instrument response information. An example is the hydrophone data associated with the Ocean Observatories network (net=OO). When these "null" response channels are requested while using the includePZ option, the Traces method will crash and not return any timeseries data. This is due to how the IRIS-WS library interacts with the irisws-sacpz service to get response information.

The result is that the exception below will crash and not return any data at all. Ideally, what ought to happen is for the library to skip past that channel's empty response information and continue to serve the timeseries data as well as the response information, when applicable.

trace = irisFetch.Traces('OO','AXCC1','*','HHZ,HDH',736696,736696+1/24/60,'includePZ','verbose');

An [MATLAB:Java:GenericException] exception occurred in irisFetch.getTheTraces() but was caught full text follows:
