Description Jan Lahoda 2011-05-16 19:18:14 UTC 
[recent sources]

Consider this:
----------
package flowtest;

public class Flowtest {

    public void i() {
        int i;
        
        try {
            i = 1;
        } catch (Exception e) {
            i = 2;
        }
        
        System.err.println(i);
    }
    
}
----------

"1" will be marked as unused, which is incorrect.

Comment 2 Jan Lahoda 2011-05-17 16:09:21 UTC 
Another example:
-----------
    public void main(String[] args) {
        int i;
        
        switch (args.length) {
            case 0: i = 0; break;
            case 1: i = 1; break;
            case 2: i = 2; break;
            default: i = 3; break;
        }
        
        System.err.println(i);
    }
