NoClassDefFoundError

....why doesn't this compile?

TestOne.java
--------------
public class TestOne {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
int x = 0;
//assert (x != 500); should break
x = 500;
}

}

Error:
-----

It does compile and run! What do you mean? Where do you try to compile/run it? Provide more information about the cintext.

hmm...it did not run somehow on my laptop, although now it ran on one of my virtual machines. Both machines run WinXP and have Java 1.6.

It is noted that the error reappeared when using the -enableassertion flag:

I had no problems compiling the code.
