Taipion client error and solution

[Freedoom]

I put this "note" because when a player leaves the game during much time can forget how the client has to be installed for working (some previous requirements).

When you use "update.jar" (from Taipion client) and if it appears the next error:

java.lang.ArrayIndexOutOfBoundsException: Index -1 out of bounds for length 1

You can fix that:
1) Installing at first place the latikai client
2) Installing JDK 11.
