Somewhere I saw a rant against java/javac allegedly using a mix of Windows and Unix style like

java -classpath ... -ea ... Something

IMHO, it is no mix, it's just like find works as well, isn't it? AFAIK, according to POSIX, the syntax should be like

java --classpath ... --ea ... Something

and -abcdef would mean specifying 6 short options at once. I wonder which version leads in general to less typing and less errors.

I'm writing a small utility in Java and in no case I'm going to use Windows style /a /b since I'm interested primarily in Unix. What style should I choose?
