java.lang.Objectxjava.lang.IJCE_ClassLoaderDepth
public class IJCE_ClassLoaderDepth
This class is a gross hack. It allows IJCE to obtain the current class loader depth (the number of stack frames after the last method in this thread that was part of a class loaded by a ClassLoader).
Since ClassLoader.classLoaderDepth()
is protected, and
since the JDK does not allow creating a security manager after one has
already been installed, this requires having code in the java.lang package.

public static int classLoaderDepth()
If there is no ClassLoader in the call stack of the current thread, -1 is returned. If there is no security manager installed, -2 is returned.
This should only be used to implement higher-level security primitives; never directly to make security decisions.
