Annotation Type Cleanup

@Target(value=LOCAL_VARIABLE)
@Retention(value=SOURCE)
public @interface Cleanup

Ensures the variable declaration that you annotate will be cleaned up by calling its close method, regardless of what happens. Implemented by wrapping all statements following the local variable declaration to the end of your scope into a try block that, as a finally action, closes the resource.

Example:

 public void copyFile(String in, String out) throws IOException {
     @Cleanup FileInputStream inStream = new FileInputStream(in);
     @Cleanup FileOutputStream outStream = new FileOutputStream(out);
     byte[] b = new byte[65536];
     while (true) {
         int r = inStream.read(b);
         if (r == -1) break;
         outStream.write(b, 0, r);
     }
 }
 

 public void copyFile(String in, String out) throws IOException {
     @Cleanup FileInputStream inStream = new FileInputStream(in);
     try {
         @Cleanup FileOutputStream outStream = new FileOutputStream(out);
         try {
             byte[] b = new byte[65536];
             while (true) {
                 int r = inStream.read(b);
                 if (r == -1) break;
                 outStream.write(b, 0, r);
             }
         } finally {
             out.close();
         }
     } finally {
         in.close();
     }
 }
 

However, in java 1.6, generating the code to do this is prohibitively complicated.
