Regarding the DRMWorkaround, can you open a PR? It will be tested on
OpenJDK7 and Oracle Java 8 by the continuous integration process, which
would give me some confidence with this topic I don't know anything
about at the current time.
Regarding Tor, we removed Tor support for the (future) 0.15 release. The
previous approach wasn't maintainable, not only but also because the
library we were using is not maintained either. At the current time, I
suggest using Tor via a socks proxy.
