     * Walks the current stack, providing {@link InspectedFrame}s to the visitor that can be used to
     * inspect the stack frame's contents. Iteration continues as long as
     * {@link InspectedFrameVisitor#visitFrame}, which is invoked for every {@link InspectedFrame},
     * returns {@code null}. A non-null return value from {@link InspectedFrameVisitor#visitFrame}
     * indicates that frame iteration should stop.

     * @param initialMethods if this is non-{@code null}, then the stack walk will start at the
     *            first frame whose method is one of these methods.
     * @param matchingMethods if this is non-{@code null}, then only frames whose methods are in
     *            this array are visited
     * @param initialSkip the number of matching methods to skip (including the initial method)
     * @param visitor the visitor that is called for every matching method
