java.lang.Object
xjava.lang.IJCE_ClassLoaderDepth
public class IJCE_ClassLoaderDepth
extends java.lang.Object
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.

classLoaderDepth
public static int classLoaderDepth()
Gets the current classLoaderDepth (assuming there is a security manager
installed). This will be 1 if this method was called
directly
by a class with a ClassLoader, 2 if there is one intervening stack
frame, etc.
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.
