I notice that this change makes Java 1.6 the minimum supported version:

    public EBacktraceIOException(Throwable t, String msg) {
        super(msg, t);
    }

This IOException constructor isn't in 1.5:

http://java.sun.com/j2se/1.5.0/docs/api/java/io/IOException.html

It's not a problem for me, but it might be worth using initCause
instead.
