Windows: PowerShell
Error: Could not find or load main class .etrap.medusa.config.ClassConfig=conf.tracer_config.xml
Cause: Windows PowerShell seems to misinterpret the class due to the -
in the command. In other words, it looks for .etrap.medusa.config.ClassConfig=conf.tracer_config.xml
instead of -Deu.etrap.medusa.config.ClassConfig=conf/tracer_config.xml
Solution: Do not use the PowerShell but switch to the Command Line.
