I have downloaded rapidminer-5.2.008.zip and unzip it. I use Ubuntu 12.04

Cannot start rapidminer:

$ cd apps/rapidminer/

~/apps/rapidminer$ echo $JAVA_HOME

~/apps/rapidminer$ java -version
java version "1.6.0_24"
OpenJDK Runtime Environment (IcedTea6 1.11.4) (6b24-1.11.4-1ubuntu0.12.04.1)
OpenJDK Server VM (build 20.0-b12, mixed mode)

Try to start:

~/apps/rapidminer$ ./scripts/RapidMinerGUI

    this is no bug of RapidMiner but of the OpenJDK that you are using.
    It seems that their implementation of

    has a serious problem. Please install another JDK and try to start RapidMiner again.
