Probably are missing files into the data folder

Code: Select all

Caused by: java.lang.NullPointerExceptionat com.l2jserver.gameserver.datatables.SkillTreesData.loadFiles(SkillTreesData.java:149)

Checking the Line 149 in SkillTreesData.java could see what is missing

Code: Select all

/**     * Loads all files type xml from data/skillTrees/ and call the parser for each one of them.     * @return {@code false} when the files are loaded.     */    private boolean loadFiles()    {        File folder = new File(Config.DATAPACK_ROOT, "data/skillTrees/");        File[] listOfFiles = folder.listFiles(new XMLFilter());        for (File f : listOfFiles)        {            loadSkillTree(f);        }        return false;    }

Game server shouldn't crash if skill trees aren't loaded:
After Changeset 5045 if skill tree folder is missing you should see:

Code: Select all

-------------------------------------------------------------------=[ Skills ]Loaded 63 Effect handlersEnchantGroupsTable: Loaded 5 groups.SkillsEngine: Loaded 65808 Skill templates from XML files.SkillTreesData: Folder C:\L2J_HIGHFIVE\game\data\skillTrees doesn't exist!SkillTreesData: Loaded 0  Class Skills for 0 Class Skill Trees.SkillTreesData: Loaded 0 Sub-Class Skills.SkillTreesData: Loaded 0 Transfer Skills for 0 Transfer Skill Trees.SkillTreesData: Loaded 0 Fishing Skills, 0 Dwarven only Fishing Skills.SkillTreesData: Loaded 0 Collect Skills.SkillTreesData: Loaded 0 Pledge Skills, 0 for Pledge and 0 Residential.SkillTreesData: Loaded 0 Sub-Pledge Skills.SkillTreesData: Loaded 0 Transform Skills.PetSkillsTable: Loaded 1815 skills.

You probably are missing the datapack folder or the configuration option that sets its path is wrong.
