All Implemented Interfaces:

Closeable, AutoCloseable

public class ApplicationClassLoader
extends URLClassLoader

The class loader used by Jikes RVM to load the application program. Since version 1.2 of the Sun API docs, the Application ClassLoader and the System Class Loader are officially the same thing. (What Jikes RVM used to call the "System Class Loader" is officially the "Bootstrap Class Loader".)

We use a two-link chain. An ordinary user's class is loaded by this class loader. This class loader first delegates to its parent (the Bootstrap Class Loader) before trying the class itself.

Renamed the former "system class loader" to the "bootstrap class loader".

numInstantiations

static int numInstantiations

createdAtBootImageWritingTime

private final boolean createdAtBootImageWritingTime

For status printing, to make sure that, if an application class loader is created at boot image writing time, it won't leak out into the next mode. This is actually not used any more, but it should never hurt, and can give one a sense of confidence when debugging Jikes RVM's classloaders.

createdWithRunningVM

private final boolean createdWithRunningVM

myName

public static final String myName

Name of the Application Class Loader. Actually used by Jikes RVM's serialization code.

I intended this name to reflect both "SystemClassLoader" and "ApplicationClassLoader".
