loadClass

                      throws ClassNotFoundException

Description copied from class: DelegatingClassLoader

Parent-first delegation without synchronizing on ClassLoader.getClassLoadingLock(String). This prevents creation/retention of per-name lock objects in a loader that does not define classes. The defining loader downstream still serializes class definition as required.

Overrides:

loadClass in class DelegatingClassLoader

Parameters:

name - The binary name of the class

resolve - If true then resolve the class

Returns:

The resulting Class object

Throws:

ClassNotFoundException - If the class could not be found

getResource

public URL getResource(String name)

Overrides:

getResource in class ClassLoader

getResources

public Enumeration<URL> getResources(String name)
                              throws IOException

Overrides:

getResources in class ClassLoader

Throws:

IOException
