I support this bug track. I had the same situation today.
The following code throws two kinds of exception, MalformedURLException and
IOException
URL url = new URL(input);
URLConnection uRLConnection = url.openConnection();
uRLConnection.connect();
netbeans shows two hints:
surround statement with try-catch
surround block with try-catch
but no "surround with multi try-catch"
it would be nice to get something like:
try {
URL url = new URL(input);
URLConnection uRLConnection = url.openConnection();
uRLConnection.connect();
} catch (MalformedURLException ex) {
Logger.getLogger(Service.class.getName()).log(Level.SEVERE, null, ex);
} catch (IOException ex) {
Logger.getLogger(Service.class.getName()).log(Level.SEVERE, null, ex);
}
after a single quick fix.

Consider a method as: private PreparedStatement getStatement() throws ClassNotFoundException, InstantiationException, IllegalAccessException, SQLException { ... } When this method is invoked in another method as: private void updateDB() { ... getStatement() ... } NetBeans IDE shows yellow bulb on "getStatement()" invocation and all the four exceptions need to be explicitly added to throws clause or surround statement/block with try/catch. An additional hint "Add all exceptions in throws clause" will be useful. On the same notes, when the statement/block is surrounded with try/catch then the following statement is included in the catch block: Logger.getLogger(SQLPreparedStatement.class.getName()).log(Level.SEVERE, null, ex); This is a perfect candidate for using multi-catch. It could be an additional hint or the default as well.
