Re: [Jython-dev] unicode test failures urllib tests etc.

Interesting. Apart from the unintentional DOS, I feel unit / regr test time
dependencies on remote resources should be limited anyway.

How are you thinking of resolving it? One way would be to keep a local copy
of the relevant file, and declare the dependency similarly to a library,
perhaps in the gradle build files. The metadata that this is a copy of
someone else’s golden source seems valuable.

Cheers

 Finally managed to get some verbose output.

./Lib/test/test_urllib2net.py:    FTP_HOST = "ftp://ftp.mirror.nl/pub/gnu/"

We're probably participating in an unintentional DOS attack via
github->travis and just being blocked.
