Examples of org.apache.tools.ant.AntClassLoader

org.apache.tools.ant.AntClassLoader
Used to load classes within ant with a different claspath from that used to start ant. Note that it is possible to force a class into this loader even when that class is on the system classpath by using the forceLoadClass method. Any subsequent classes loaded by that class will then use this loader rather than the system class loader. @author Conor MacNeill @author Jesse Glick @author Magesh Umasankar
