I tested it. You can check with this:
if (Thread.currentThread().getName().equals("main")) {
    // do something
}

Strangely, == doesn't work, but .equals() does. == probably compares the object, not the contents of the string.

Well, I suppose you could store the name of the thread in a global variable when the program first starts in main(), because you know for sure you're in the main thread then. Then you can compare to the stored value later.

Oh, so this isn't just a Java application, this is some Eclipse thing? Then I don't know. Just use "main" and fix it when it breaks Smile (unless there's a better solution that I don't know of).

if this thing breaks, there's a good chance it would take eclipse down with it. so i can't risk it:)
