Consider the following Java snippet:
try {
    URL url = new URL("http://www.example.com"); // [1]
    URLConnection conn = url.openConnection(); // [2]
    // etc.
} catch (MalformedURLException mue) {
    // handle mue
} catch (IOException ioe) { // [3]
    // handle ioe
}
Enable highlighting of Exception Throwing Points (Options > Editor > Highlighting).
If I put the caret over IOException in line [3], both "new URL(...)" in line [1] and "url.openConnection()" in line [2] get highlighted. I think that only [2] should be highlighted, because there exists a previous catch clause that catches the exception thrown by [1].
