There is a lot of bad code out there and this method will clear up the know problems. This method should only be called when the class loader will no longer be used. It this method is called two often it can have a serious impact on preformance. clearSunJarFileFactoryCache public static void clearSunJarFileFactoryCache(String jarLocation)(Code) clearSunSoftCache public static void clearSunSoftCache(Class clazz, String fieldName)(Code) Clears the caches maintained by the SunVM object stream implementation. This method uses reflection and setAccessable to obtain access to the Sun cache. The cache is locked with a synchronize monitor and cleared. This method completely clears the class loader cache which will impact preformance of object serialization. Parameters:   clazz - the name of the class containing the cache field Parameters:   fieldName - the name of the cache field createClassLoader public static URLClassLoader createClassLoader(String appId, URL[] urls, ClassLoader parent)(Code) createTempClassLoader public static URLClassLoader createTempClassLoader(ClassLoader parent)(Code) createTempClassLoader public static URLClassLoader createTempClassLoader(String appId, URL[] urls, ClassLoader parent)(Code) destroyClassLoader public static void destroyClassLoader(ClassLoader classLoader)(Code) destroyClassLoader public static void destroyClassLoader(String appId)(Code) getContextClassLoader public static ClassLoader getContextClassLoader()(Code) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
