Java Connection Problems

[fsilberberg]

Let me chime in as an FTA and WPILib developer. None of the officially supported languages (or Python or C# for that matter) take any longer than the others to connect on the field. @bdaroz has a good summary of the events that go on after a match, although FIRST has made some improvements to the radio configuration step. Last year configuration only took 15-30 seconds. The main bottleneck for connecting to the field in 2016 was radio boot time: While being far more reliable in operation than the dlink's were, they take a long time to start up.

Now, that's not to say that it isn't possible to create code that takes a very long time to start up and go green on the field. Java, like any language, can be abused. But if you're using the standard WPILibJ templates and not going too crazy, you should be fine.
