protected java.lang.Class<?> findClass(java.lang.String name)
                                throws java.lang.ClassNotFoundException

Overrides:

findClass in class java.net.URLClassLoader

Throws:

java.lang.ClassNotFoundException

protected java.lang.Class<?> loadClass(java.lang.String name,
                                       boolean resolve)
                                throws java.lang.ClassNotFoundException

overridden to maintain a list of classes that are loaded by this (or a child) Classloader to be able to clear references of this classes (during stop() ) In addition to that we hold a list of ALL loaded classes as a cache.

Overrides:

loadClass in class java.lang.ClassLoader

Throws:

java.lang.ClassNotFoundException

findResource

public java.net.URL findResource(java.lang.String name)

Overrides:

findResource in class java.net.URLClassLoader

start

public void start()

stop

public void stop()

Stops this classloader. this will "stop" the underlaying platform which means that

the connection pools are closed all timer tasks stopped (if cronjob extension is installed) the cache is cleared all fields of static classes are nulled (due to GC problems)

clearAllReferences

public void clearAllReferences()

Null out any static or final fields from loaded classes, as a workaround for apparent garbage collection bugs

addClassPathURLs

protected void addClassPathURLs(java.util.List<java.net.URL> urls,
                                java.lang.String classpath)
                         throws java.net.MalformedURLException

Throws:

java.net.MalformedURLException

buildURL

protected java.net.URL buildURL(java.io.File f,
                                YURLClassLoader.TYPE type)
                         throws java.net.MalformedURLException

Throws:
