okay, understood, thanks Karl.

i have learned how to avoid the stackoverflow error caused by circular
injection, but just recently, I made a change in my software/project, and i
experienced the stackoverflow error, and at first, i did not know what
caused the exception, but then I ran a local test, and read the
stacktrace...in netbeans error/output console...on my development server.
the stacktrace (on the production server) was a bit too long for me to
decipher; evidently, tomee/tomcat localhost log and/or stderr/catalina logs
are easier to read in netbeans output/error console for tomee server. :)
