Constructor Detail

EmbeddedURLClassLoader

public EmbeddedURLClassLoader(URL[] urls)

Fixes the class loading in APT to be embeddable. To load a factory, APT is doing something like

 ClassLoader classLoader = new URLClassLoader( classPath );
 AnnotationProcessorFactory factory = (AnnotationProcessorFactory) classLoader.loadClass( name );
 

i.e. it's assumed that AnnotationProcessorFactory is present in the system class loader. This is generally wrong so we derive the factory class loader from the APT class loader.
