Hi Christian,
In addition to Chau's replay the official information is published in the PAM and the read me for the corresponding version of LoadRunner and running of Java VUser on Unix LGs is currently not supported.
Additionally when you install your load generators, please make sure that you use supported version of the operating system.
LoadRunner product availability matrixes are available from the following link: http://support.openview.hp.com/sc/support_matrices.jsp#LR
Kind regards,
Vesela
