You have empty config in properties. If you can't find it, then check Config.java 1116 line and see which one it is.

i mean im in 1116 what could be wrong here:

			           FACTION_SYSTEM_FIRST_FACTION_TITLE_COLOR = Integer.decode("0x" + players.getProperty("FirstFactionTitleColor", ""));

Told ya, empty config.. You miss the color.

Dude, to read an error (and don't be salty, you will read actually A LOT, notably YOUR OWN errors) you simply have to read the first line of it, and then you have to seek in the stacktrace the first line referencing to project files.

 

If you're new to Java, easiest is to seek Google for Exception type, each exception got it's own type. NumberFormatException meaning seems obvious even for a rookie (Java is enough verbose for that ; until you suck at english, but that's another problem). Then we got Integer parse logic, which means the program stucked into a int parse. Then the first line of actual L2J is Config.load(Config.java:1116) which gives you the method name, the class name and the line.

 

The most common Exception is NullPointerException (NPE), aka an object which is supposed to be filled, but is actually null (= not even initialized) on execution time.

 

Also Javadoc is a serious help, and stackoverflow website is full of gold. If you type a question on google, you probably will have a stackoverflow question/answer on it.

 

About your line

FACTION_SYSTEM_FIRST_FACTION_TITLE_COLOR = Integer.decode("0x" + players.getProperty("FirstFactionTitleColor", ""));

The "default to use" property is empty, aka "". So both that parameter (which is a backup value, if .properties one was missing) is missing but you also missed the .properties one. Two really basic errors, and as said Sdw if you already whine about that, be assured you will whine forever. Because harder will be your problem, less detailed answer you will receive (both in quantity and shape).

Ehh, you got the line, I told it's empty. Dunno what you expect more.

 

Locked.
