The Oracle praxis is that the year or years should still be followed by a comma. E.g:

 Copyright (c) 2018, Oracle and/or its affiliates. All rights reserved.
or
 Copyright (c) 2001, 2018, Oracle and/or its affiliates. All rights reserved.

I don’t know if this is an Oracle quirk or and (in)official OpenJDK requirement, but it probably doesn’t harm to follow it. :-)
