The Ranorex Java Plug-In allows testing of Java Swing and Java AWT applications. With Ranorex 5.0.0 and higher, the instrumentation will be enabled automatically. If you have instrumented your Java Runtime Environment using the Ranorex Instrumentation Wizard of a previous Ranorex version, it's recommended to deactivate the obsolete instrumentation. To do so, either use the Java instrumentation wizard or manually delete the Plug-In specific files as shown below.
