Re: FW: Java Vs RPG on iSeries

Sorry Mr. Pluta,

excuse me, I didn't recognize that this is a rpg hardliner mailing list. It's
foolish, that a statement pro java is flame in a java-400l mailing list. And
its foolish, that I have to declare a man, who is teaching java, what is
multithreading, sorry, I won't do again.
