OutOfMemoryException when using WEKA 3-6 under Windows 7

Weka is a collection of machine learning algorithms for data mining tasks. This software can be used by students who participate in the class "Machine Learning" at TU Wien. When the Weka-User executes memory-intesitive tasks (e.g. visualizes results of a machine learning algorithm), Weka is very likely to throw an OutOfMemoryException. As a result to the exception the software crashes. This execption is absolutely repeatable. The Weka-User will get the exception at every time he executes the sequence of operations which had previously lead to the exeception. That is why there is no way to workaround this error without having to disclaim using Weka. The OutOfMemoryException is not only limited to Weka 3-6 on Windows 7.
