All Implemented Interfaces:

Closeable, AutoCloseable

public class CheckingClassLoader
extends URLClassLoader

This ClassLoader is used to load classes that are not to be reloaded but which must cause the classes they load to pass thru the checking mechanism. Classes loaded by this class have their classloader set to this class, and every time such a class needs another class that other class passes thru the "must I reload this class" check too. Classes loaded by this loader are not discarded; the classloader exists only to force other classloads thru a check.

This classloader loads classes as follows:

• If a class is already known we're done
• If a class is part of the system (java.*, javax.*) we load thru a system loader always
• All other classes are checked against the inclusion/exclusion patterns.
• Excluded classes are loaded thru this classloader, so classes they load can be checked.
• Included classes are loaded thru the DISCARDABLE classloader.
