Direct Known Subclasses:

Enclosing class:

private class ContextLocal.Fallback
extends java.lang.Object

A wrapper of the context-local value kept in the ContextLocal.fallback thread-local storage. This is used as backing storage for this context local variable when no security environment is present. This implementation is necessary to allow the fallback thread local variable's initialValue method to invoke the enclosing class' implementation (which may have been overridden by a subclass).
