All developers have been notified to change their header, so all new files will use the new header.
This jira is to fix the existing files.

1) In java, drl, js and css files, replace in path this Case Sensitive Regular Expression in IntelliJ:

^/\*\n \* Copyright (\d{4}) JBoss Inc\n

by with this

/*\n * Copyright $1 Red Hat, Inc. and/or its affiliates.\n

To understand the regex, read this:
https://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html

Commit that already before starting step 2. I even recommend doing a separate commit per file type. (But wait with pushing until all are fixed.)

2) Then look for the string "JBoss Inc" in all files, case insensitive. Fix those too if applicable. Either by another smart regex find-replace or manually.

3) Do step 1) and step 2) again for "JBoss by Red Hat." instead of "JBoss Inc"
