It sounds like the cache is in a static variable in the Java class, hence in the CF classloader.
However, a quick peruse of the documentation for java.awt.Toolkit reveals that getImage will cache images indefinitely, but the underlying createImage will not: "Since the mechanism required to facilitate this sharing of Image objects may continue to hold onto images that are no longer of use for an indefinite period of time, developers are encouraged to implement their own caching of images by using the createImage variant wherever available." http://java.sun.com/j2se/1.4.2/docs/api/ http://www.google.com.au/search?hl=en&q=java.awt.toolkit+%22image+cache%22&b tnG=Search&meta= Jaime Metcher > -----Original Message----- > From: Robert Harrison [mailto:[EMAIL PROTECTED] > Sent: Thursday, 6 September 2007 4:48 AM > To: CF-Talk > Subject: RE: Clear Object Variables > > > > Did you try my suggestion to re-run the constructor? > > Yes.
