+<DD>Verifies that the specified object can be trusted to correctly implement
+ its contract, using verifiers from the specified class loader and
+ using the specified collection of context objects as necessary. If a
+ <code>null</code> class loader is specified, the context class loader
+ of the current thread is used instead. Code that is itself downloaded
+ and that carries its own trust verifiers (to trust other downloaded
+ code) should specify an explicit class loader unless the calling code
+ is known to be reachable from the context class loader.
+ <p>
+ A <A HREF="../../../net/jini/security/TrustVerifier.Context.html" title="interface in net.jini.security"><CODE>TrustVerifier.Context</CODE></A> is created, containing an ordered list
+ of trust verifiers (obtained as specified below) and the specified class
+ loader and collection of context objects. The
+ <A HREF="../../../net/jini/security/TrustVerifier.Context.html#isTrustedObject(java.lang.Object)"><CODE>isTrustedObject</CODE></A> method
+ of that context is then called with the specified object. If that call
+ returns <code>true</code>, then this method returns normally. If that
+ call throws a <code>RemoteException</code> or
+ <code>SecurityException</code> exception, that exception is thrown by
+ this method. If that call returns <code>false</code>, a
+ <code>SecurityException</code> is thrown.
+ <p>
+ The collection of context objects is provided as a means for the
+ caller to communicate additional information to the trust verifiers.
+ The meaning of an element in this collection is determined by its
+ type. As a specific example, if any trust verifiers might communicate
+ with a remote server (in particular, when verifying a proxy for a
+ remote server), the caller might be responsible for specifying any
+ necessary client constraints as a context object of type
+ <A HREF="../../../net/jini/core/constraint/MethodConstraints.html" title="interface in net.jini.core.constraint"><CODE>MethodConstraints</CODE></A>.
+ <p>
+ When security is a concern, this method should be called with a
+ downloaded proxy before making any other use of the proxy, in order to
+ verify basic trust in the proxy to correctly implement its contract.
+ This method can also be used to verify trust in other types of objects,
+ depending on what verifiers have been configured. In general,
+ verification of an object involves verification of all of its
+ constituent objects. However, for objects that are instances of
+ <A HREF="../../../net/jini/core/constraint/RemoteMethodControl.html" title="interface in net.jini.core.constraint"><CODE>RemoteMethodControl</CODE></A>,
+ the client constraints (that would be returned by
+ <A HREF="../../../net/jini/core/constraint/RemoteMethodControl.html#getConstraints()"><CODE>RemoteMethodControl.getConstraints</CODE></A>) are not verified; it is assumed
+ that the caller will either replace them or independently decide that
+ it trusts them. Verification of other types of objects may similarly
+ exempt certain application-controlled state.
+ <p>
+ The list of trust verifiers is obtained as follows. For each resource
+ named
+ <code>META-INF/services/net.jini.security.TrustVerifier</code>
+ that is visible to the specified class loader, the contents of the
+ resource are parsed as UTF-8 text to produce a list of class names.
+ The resource must contain a list of fully qualified class names, one per
+ line. Space and tab characters surrounding each name, as well as blank
+ lines, are ignored.  The comment character is <tt>'#'</tt>; all
+ characters on each line starting with the first comment character are
+ ignored. Each class name (that is not a duplicate of any previous class
+ name) is loaded through the specified class loader, and the resulting
+ class must be assignable to <A HREF="../../../net/jini/security/TrustVerifier.html" title="interface in net.jini.security"><CODE>TrustVerifier</CODE></A> and have a public
+ no-argument constructor. The constructor is invoked to create a trust
+ verifier instance. An implementation of this method is permitted to
+ cache the verifier instances associated with a class loader, rather than
+ recreating them on every call.

+ control context, and restoring any additional context encapsulated by the
+ <code>SecurityContext</code> instance--should be performed in conjunction
+ with a single <code>AccessController.doPrivileged</code> call, as
+ illustrated below:
+ <pre>
+      // snapshot context
+      SecurityContext ctx = Security.getContext();
+
+      // restore context
+      AccessController.doPrivileged(
+          ctx.wrap(action), ctx.getAccessControlContext());
