On the other hand, putting a license header in a META-INF file is absurd, this type of file is purely functional and unlikely to be copyrightable anyway. I suggest patching the tomcat9 package to remove the comment from res/META-INF/jasper-el.jar/services/javax.el.ExpressionFactory if that improves the backward compatibility. Emmanuel Bourg
