Bug testing this now.

Replicated, here is a fixed snapshot; http://ci.craftationgaming.com/job/ItemJoin/489/

Let me know!

Very weird, seems that Java was bypassing my catch exception to use the legacy methods for skull items. Wasn't able to replicate it on my end but I have seen similar instances of ignoring catch exceptions before.

I designed a better method to catch and use the legacy skull methods so it should now work in the latest snapshot; http://ci.craftationgaming.com/job/ItemJoin/490/

Let me know, sorry about that!

Plugin Version: 5.0.7-SNAPSHOT-b490

pd: Only happen when online-mode: false

Should now function in this version; http://ci.craftationgaming.com/job/ItemJoin/491/

Seems the player was being returned as having not played the server before so I made it simply apply the owner string. If you are using SkinRestorer its likely the skin will be a steve/alex until their API is fixed but you will only know from testing.

Yes! you got it!
