Thank you for your answer. I looked at this and found that this is a problem in geotools. When the WKT string is parsed the single quotes are changed to double quotes and the CRS factory doesn't like that. So I patched this part of geotools to get around this problem. The question remains why the NetCDF plugin looks at the lon variable at all. That one is included in the crun variable that has the projection defined.
