Need help with warning on gameserver. (ubuntu)

[dasoldier]

hello l2j server community,

I have a little problem after i moved the server from Win7 to Ubuntu server 12.04.1 LTS.

Everything runs fine and i can login without a problem.
but the gamserver gives this warning while starting up:
The system property sun.awt.backingStore is not set,by default backingStore=NotUsefull

This are the commands ive used so far connected to java.

sudo apt-get purge oracle-java7-installer*
sudo apt-get install python-software-properties
sudo apt-get update
sudo add-apt-respository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer

O can check the version trough command "java -version"
Results:
Java(TM) se runtime environment (build 1.7.0_13-b20)
Java hotspot(TM) 64-Bit Server vm (build 23.7-b01, mixed mode)

I hope someone can help me with this,

Greetings,
Dasoldier

install things from repositories is not recommended always, because generally all the repositories in Linux are outdated.

better download binary files from oficial websites and install the stable releases.

Hey melerix,
Thanx for the fast reply,

Oke ive removed the repositories.
Ive downloaded jdk-7u13-linux-x64.tar from the oracle website.
After unzipping ive moved the files to /usr/lib/jvm/jdk1.7.0

And executed these commands
sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.7.0/bin/java" 1
sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.7.0/bin/javac" 1
sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jdk1.7.0/bin/javaws" 1

Rebooted ubuntu and after starting the gameserver, the same warning appears.

[MELERIX]

weird, no idea what could be causing it then, but well... is just a warning and if don't cause issues to the gameserver, don't worry about it then.

[dasoldier]

Yea you should be right

I will give a response when ive figured it out somewhere in the future.
Thanks for the help so far ^^
