Hello everybody !

 

After every server restart clans can't be restored.

The error is :

 

Error while restoring clan : java.lang.NullPointerException

(This error is repeated for every clan)

the next line is :

Restored 8 clans from database

clan exists in clan_data but is like there is not!

 

It comes from net.sf.l2j.gameserver.model.L2Clan.java and the file is 100% unmodified!

I am sure I was using this pack in the past without problems. Now I just re-compiled the source!

 

I was thinking if it's the problem comes from jdk version but I tried to run the server and compile the source with jdk6 , jdk7 and jdk8

 

Any idea? thank you in advance

Check log folder for detailed info about the npe. Then check that file and provide the line. And whats the pack.

the error is not saved in the error log.

just another one coming from clans

pack is old based in L2jteon as far I remember

 

setLevel(L2Clan.java:805)

 

  
public void setLevel(int level)
    {
        _level = level;
        if(_forum == null)
        {
            if(_level >= 2)
            {
                _forum = ForumsBBSManager.getInstance().getForumByName("ClanRoot").getChildByName(_name);
                if(_forum == null) // Line 806
                {
                    _forum = ForumsBBSManager.getInstance().createNewForum(_name,ForumsBBSManager.getInstance().getForumByName("ClanRoot"),Forum.CLAN,Forum.CLANMEMBERONLY,getClanId());
                }
            }
        }
    }

I see it's ok ( I never modified this file , and it was working fine)

sorry for double post .

I tried //pledge setlevel 1 and it works fine

//pledge setlevel 2-5 is not!

Put this

                if(_forum == null) // Line 806
                {
                    _forum = ForumsBBSManager.getInstance().createNewForum(_name,ForumsBBSManager.getInstance().getForumByName("ClanRoot"),Forum.CLAN,Forum.CLANMEMBERONLY,getClanId());
                }

Under if (_forum != null)

            if (_forum != null)
            {
                if(_forum == null) // Line 806
                {
                    _forum = ForumsBBSManager.getInstance().createNewForum(_name,ForumsBBSManager.getInstance().getForumByName("ClanRoot"),Forum.CLAN,Forum.CLANMEMBERONLY,getClanId());
                }
            }

Or simply use (fix errors if any) this one

    public void setLevel(int level)
    {
        _level = level;
        
        if (_level >= 2 && _forum == null)
        {
            final Forum forum = ForumsBBSManager.getInstance().getForumByName("ClanRoot");
            if (forum != null)
            {
                _forum = forum.getChildByName(_name);
                if (_forum == null)
                    _forum = ForumsBBSManager.getInstance().createNewForum(_name, ForumsBBSManager.getInstance().getForumByName("ClanRoot"), Forum.CLAN, Forum.CLANMEMBERONLY, _clanId);
            }
        }
    }
