You're saying it's equivalent to "VMSecurityManager.getClassContext()[1]" ?
There are several instances of that expression in Classpath, so this
optimization may indeed be useful. (This is an orthogonal issue from
the one I originally asked about, but I agree with you).

But what about:

 Foo.method()->Method.invoke()->Runtime.loadLibrary()->getCallerClassLoader()

Is the "caller's" class supposed to be "Foo" or "Method" ? This is something
that is not made clear in the documentation to getClassContext().
