The DAS (version 1) test that relies on this URL - http://genome.cse.ucsc.edu/cgi-bin/das/dsn - is now failing.
We should remove this test or create a mock object that will allow the test of our code to proceed even if the data source is not available.
However, since the UCSC DAS service is no longer actively supported at UCSC, we should eliminate it from the code base. The UCSC DAS1 server was the only DAS service available, so we should probably remove it from the code base.
Note: Removing DAS1 support will affect many places in the code, notably:
- Places where default data sources are configured - see IGB Preferences JSON file
- DAS module itself: "Core - DAS (data source) module"
- POM files that declare dependencies on the DAS module within IGB
