Java's garbage collection cannot be relied on to clean up everything. Specifically, subclasses of ``++org.eclipse.swt.graphics.Resource++`` must be manually ``++dispose()++``-ed when you're done with them.
|
|
|
|
Particularly for the ``++Image++`` subclass, which retains an open ``++FileHandle++`` for the life of the instance, failure to properly ``++dispose++`` of ``++Resource++``s can result in a resource leak which could bring first the application and then perhaps the box it's on to their knees.

public class MyLeakyView {

Image myImage = new Image("image/path"); // Noncompliant; not disposed
