Briar crashes when TorPlugin tries to create a connection

java.lang.NullPointerException: Attempt to write to field 'java.io.OutputStream net.sourceforge.jsocks.Proxy.out' on a null object reference

In the library sources that Gradle downloaded for me, it looks like the proxy field of the jsocks SocksSocket constructor is ignored completely, but the doDirect() internal function called by that constructor uses the unset proxy variable. This looks like an upstream bug. I don't know how this is working for anyone else, given that the jsocks library is verified by Gradle Witness.
