As ModuleSourceLauncherTests creates files on the default file system and spawns JVMs via the `java` launcher, there might be IO related issues?

I will not bump timeout on this test as the junit printout shows a total timeout of all junit tests together taking /much/ less time than 120 seconds

It is possible we need to extend the timeout after JDK-8260555
