Add log4j.skipJansi to prevent Log4j from initializing a Jansi
terminal. It is redundant because this is handled by TCA and it
will be only active for a few seconds until TCA is loaded.
* Delay switch to new server until after JoinGame is sent.
Unfortunately, in some cases (especially vanilla Minecraft) some login
disconnects are sent after ServerLoginSuccess but before JoinGame.
We've been using ServerLoginSuccess but it has caused too many problems.
Now Velocity will switch to a stripped-down version of the play session
handler until JoinGame is received. This handler does very little by
itself: it simply forwards plugin messages (for Forge) and waits for the
JoinGame packet from the server.
This is an initial version: only vanilla Minecraft 1.12.2 was tested.
However this is the way Waterfall without entity rewriting does server
switches (which, in turn, is inherited from BungeeCord).
* Move to Gradle 5 and Error Prone.
Updating Checker Framework flagged numerous warnings, which have been
corrected. These probably involve type declarations lacking a nullness
annotation that appeared elsewhere.
The Velocity API has had a lot of community input (special thanks to @hugmanrique who started the work, @lucko who contributed permissions support, and @Minecrell for providing initial feedback and an initial version of ServerListPlus).
While the API is far from complete, there is enough available for people to start doing useful stuff with Velocity.
