Bug ID 4180369 says URLClassLoader cached jar files (jar_cacheXXX.tmp) should be deleted on exit as of 1.2fcs(File.deleteOnExit).

This isn't happening.  Run the attached application and check your temp directory - it leaves the jar_cache file after exiting.  Use "jar tvf" to view the contents of the jar_cache file to verify it is the one specified in the URL in the source code.


import java.net.*;
public class JarCacheJunk {
	public static void main(String args[]) throws Exception {
		URL urls[] = new URL[1];
		urls[0] = new URL("http://morechat.talkcity.com/java/ezclasses/ezlite.jar");
		URLClassLoader cl = new URLClassLoader(urls);
		Class cls = cl.loadClass("lw.ezlite.EZLite");
		System.exit(0);
	}
}
