[THREDDS #QYJ-871636]: Re: DAP2Exception questions

First, change the catch(Exception e) to catch(Throwable e).
It is barely possible that the Dap2Exception is getting re-thrown
in some other form.

Second, we need to trace the headers for the http response.
One possibility is to use wireshark (I think that is the name).
Another is to see if you can use any of the suggestions here:
https://stackoverflow.com/questions/12364555/how-i-can-i-display-all-the-http-headers-when-using-the-defaulthttpclient

If you cannot do any of these, then I will send you a custom version
of ServerVersion.java that will show more debug info. What version of Java
are you using?
