PyCharm ругается при запуске вот так

[cc lang=”bash”]developer-HP bin # ./pycharm.sh
OpenJDK Runtime Environment (IcedTea6 1.11pre) (6b23~pre11-0ubuntu1.11.10.1)
OpenJDK Client VM (build 20.0-b11, mixed mode, sharing)
WARNING: You are launching IDE using OpenJDK Java runtime.

THIS IS STRICTLY UNSUPPORTED DUE TO KNOWN PERFORMANCE AND GRAPHICS PROBLEMS!

NOTE: If you have both Oracle (Sun) JDK and OpenJDK installed
please validate either PYCHARM_JDK, JDK_HOME, or JAVA_HOME environment variable points to valid Oracle (Sun) JDK installation.
See http://ow.ly/6TuKQ for more info on switching default JDK

Press Enter to continue.[/cc]

Решается проблема просто
Ставим JRE
[cc lang=”bash”]apt-get install sun-java6-jdk sun-java6-jre[/cc]
и выбираем дефолтную жаву
[cc lang=”bash”]
$ sudo update-alternatives –config java
There are 2 choices for the alternative java (providing /usr/bin/java).

Selection Path Priority Status
————————————————————
* 0 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 auto mode
1 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 manual mode
2 /usr/lib/jvm/java-6-sun/jre/bin/java 63 manual mode[/cc]

Выбираем 2 и жмём энтер.
