Comment 2 Martin Entlicher 2013-12-16 16:03:34 UTC 
To reproduce:

public class TestUnionExcs {
    
    public static void main(String[] args) {
        try {
            args[2].charAt(10);
        } catch (ArrayIndexOutOfBoundsException | NullPointerException ex) {
            String msg = ex.getMessage().trim(); // Put breakpoint here
            System.err.println(msg);
        }
    }
}

Debug that class, after it stops on the breakpoint, do Step Over Expression. The exception is thrown then.
