Enclosing class:

ChicoryPremain

public static class ChicoryPremain.ChicoryLoader
extends ClassLoader

Classloader for the BCEL code. Using this classloader guarantees that we get the PAG version of the BCEL code and not a possible incompatible version from elsewhere on the users classpath. We also load daikon.chicory.Instrument via this (since that class is the user of all of the BCEL classes). All references to BCEL must be within that class (so that all references to BCEL will get resolved by this classloader). The PAG version of BCEL is identified by the presence of the PAG marker class (org.apache.bcel.PAGMarker). Other versions of BCEL will not contain this class. If other versions of BCEL are present, they must appear before the PAG versions in the classpath (so that the users application will see them first). If only the PAG version is in the classpath, then the normal loader is used for all of the classes.
