Re: Error occurring in dods.dap.Parser

Unfortunately that seems to break thredds's parsing of catalogConfig.xml.

If I convert
<dataset name="Single-level Salinity Data" 
urlPath="stream=ocea,param=200,DATE=20000101,TIME=0000,STEP=0,EXPVER=0oc7,CLASS=RD,TYPE=AN,NUMBER=0,METHOD=0,LEVELIST=7.000,LEVTYPE=DP,REPRES=LL,DOMAIN=G,salinity.nc"/>

to

<dataset name="Single-level Salinity Data" 
urlPath="stream%3Docea,param=200,DATE=20000101,TIME=0000,STEP=0,EXPVER=0oc7,CLASS=RD,TYPE=AN,NUMBER=0,METHOD=0,LEVELIST=7.000,LEVTYPE=DP,REPRES=LL,DOMAIN=G,salinity.nc"/>

that is to change the first "=" to %3D, the hex code for "=", it seems 
to break the lookup. What I get is the error

Error {
   code = 1;
   message = "Dataset not found in catalog; urlPath= 
<stream=ocea,param=200,DATE=20000101,TIME=0000,STEP=0,EXPVER=0oc7,CLASS=RD,TYPE=AN,NUMBER=0,METHOD=0,LEVELIST=7.000,LEVTYPE=DP,REPRES=LL,DOMAIN=G,salinity.nc>";
};


It would seem that thredds is converting the %3D to "=" in its head, 
then failing on the string comparison. Just my guess though.
