> The Drools example project contains code snippets that yield warnings: *while I absolutely understand that resources are limited and examples might not be the priority and the core code of the engine is of good quality*, I do think it is important to display dedication to high quality products. 
> Having an example project full of code quality issues just gives a very bad first impression of the whole Drools project...
> Examples: 
> {code:title=org.drools.examples.cashflow.CashFlowMain|borderStyle=solid}
> public class CashFlowMain {
>     public static void main(String[] args) throws Exception {
>         SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
> {code}
> yields {color:red}WARNING: The value of the local variable sdf is not used {color}
> {code:title=org.drools.examples.sudoku.Sudoku.dumpGrid()|borderStyle=solid}
>     /**
>      * Nice printout of the grid.
>      */
>     public void dumpGrid() {
>         Formatter fmt = new Formatter(System.out);
> {code}
> yields {color:red}WARNING: Resource leak: 'fmt' is never closed {color} 
> {code:title=org.drools.games.pong.PongUI|borderStyle=solid}
> import java.awt.*;
