Description Volker Berlin CLA 2017-09-06 09:13:00 EDT 
If the plugin Java 9 Support (BETA) is installed then the sequence of jar files and project in the classpath is garbaged. Changing on the order in the definition of the launcher in the run configuration has no effect. 

It look like it was iterated over an HashSet to generate the classpath parameter.

After uninstalling the plugin the order is correct.

Ok, I have now:

  Eclipse JDT (Java Development Tools) Patch with Java 9 support (BETA) for Oxygen development stream	1.1.1.v20170904-1938_BETA_JAVA9


There is no difference. The order in the classpath of the launcher is wrong.
