Hello @yesamer. I used a bash script (check_header.sh) to check the headers using the kie-tools-rad-report file.

check_header.sh
kie-tools-rad-report.txt

To use the script:
Paste the file check_header.sh to kie-tools directory
Paste the file kie-tools-rad-report.txt to kie-tools directory
Run check_headers script ($./{kie-tools directory}/./check_header.sh.

Here is the list of files without headers I found:
results.txt
Although it is possible that some of the files could be ignored, there are lots of .java files that are likely to be problematic.

Thank you @Josephblt for checking!!
I intentionally ignored some java files because:

• In dashbuilder, a set of java files are used to test a code generation feature, and adding the headers leads to some tests failures
• Some java class file are a copy from other libraries. In such a case I don't know how to handle that

In any case, I'll double check again
