Removing unnecessary (?) jars from exported apps: ok if it still runs?

Is it save to delete the jogl-*.jar files (OpenGL?) from exported apps if the apps still start afterwards and appear to work normally across Windows/Linux/MacOS? In other words: Would there be a startup failure if these files were really needed (rather than a run-time failure under special circumstances which I couldn’t all test)?

If I were you, I would remove them. I am saying this from experience and from my limited exposure to Processing’s source code.
