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.
