java version "1.3.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-b24)
Java HotSpot(TM) Client VM (build 1.3.1-b24, mixed mode)

The following code compiles without error:

*/
public class BadDay {
        public static void anyMeth() {
                for(int i=0; i<10; i++); // comment me
                for(int i=i; i<10; i++);
        }
        public static void main(String [] as) { }
}
/*

The first indication of a problem is when you run the program; the ClassLoader
gives you this obscure message:

    Exception in thread "main" java.lang.VerifyError: (class: BadDay, method:
    anyMeth signature: ()V) Accessing value from uninitialized register 1


If you comment out the "comment me" line, the compiler correctly reports:

    BadDay.java:7: variable i might not have been initialized
                    for(int i=i; i<10; i++);
                              ^
    1 error
