In this PR, I replicate what @Azquelt did in jakartaee/cdi-tck#528

I generated the 2nd commit using this script:

mvn -pl . -fn org.apache.rat:apache-rat-plugin:0.16:check -Drat.excludeSubprojects=false

for F in $(grep -h ????? target/rat.txt | grep \\.java | sed -e 's| !????? ||') ; do
  data=$(git log --format="%ae %as" $F | tail -1)

  if [[ $data =~ redhat || $data =~ starksm || $data =~ pmuir || $data =~ antoine || $data =~ marlow ]] ; then
    company="Red Hat, Inc."
  elif [[ $data =~ ibm ]] ; then
    company="IBM Corp."
  else
    exit 1
  fi
  
  year=$(echo $data | cut -d ' ' -f 2 | cut -d '-' -f 1)
  
  cat > tmp.txt <<EOF

  cat $F >> tmp.txt
  mv tmp.txt $F
done

Running the (somewhat more manual) script I used for jakartaee/cdi-tck#528, I see no differences in the Java files between my workspace and this PR.

I suggest to use: Eclipse Foundation and individual contributors instead of maintaining a particular company name. In this way, all new files will use the same header. Besides, I don't see any advantages of using a particular company.

[Ladicek]

No.

[Emily-Jiang]

I think I have expressed my opinion clearly. For Red Hat contributions, obviously the contributors have choose to use the copyright header to Red Hat, which is fine. I suggest for the contributors otherwise Red Hat are free to use contributors to Eclipse Foundation for easier maintenance.
