Class SunAwtAppContextInitiator

java.lang.Object

se.jiderhamn.classloader.leak.prevention.preinit.SunAwtAppContextInitiator

All Implemented Interfaces:

PreClassLoaderInitiator

public class SunAwtAppContextInitiator
extends Object
implements PreClassLoaderInitiator

There will be a strong reference from sun.awt.AppContext#contextClassLoader to the classloader of the calls to sun.awt.AppContext#getAppContext(). Avoid leak by forcing initialization using system classloader. Note that Google Web Toolkit (GWT) will trigger this leak via its use of javax.imageio.
