Why do I keep getting “Evaluations must contain either an expression or a block of well-formed statements”?

Question

In my code, I am trying to output the value of src in the expressions window.

public void doIt() {
    String src = \"test\";
    System.out.pri

I just spent TONS of time to figure out that if you will create a package "Foo" and inside this package you'll create class called "Foo", like this:

package Foo;

public class Foo{
    public Foo () {};
}

After the point when you use this class first time in your program, you will not be able to use expressions anymore:

import Foo.Foo; //this is the devil i think

public static void main(String[] args){
    EventQueue.invokeLater(new Runnable(){
        public void run(){
            //debug expressions works fine
            Foo tmp = new Foo();
            //debug expressions wouldn't work anymore
        }
    });
}

This bug can be reprodused up to current Eclipse Neon 4.7.
