The toolkit (PartialCompositeContext) calls getEnvironment()
at the start of each context method. Since the LDAP provider
clones the environment before returning it, this imposes
an extra copy of the environment Hashtable each time
you invoke a context method. That's bad for performance.

There are also a few places where getEnvironment() is still not
conforming to spec and not returning a clone:
HierMemDirCtx
GenericURLContext
RegistryContext
CNCtx

Also, in PartialCompositeContext, there are 3 constants that are
being declared as protected final. Add 'static' modifier to them:
    protected final int _PARTIAL = 1;
    protected final int _COMPONENT = 2;
    protected final int _ATOMIC = 3;
