In the previous section I presented a strategy that allows you to trace through your application's execution using a ThreadLocal variable that records method actions: start, stop, or exceptional exit. Before we dive into using bytecode instrumentation to add tracing to an application, this section provides a sample application that manually uses the tracing library so that we can better understand what we want the bytecode instrumentation to accomplish. In the next section we'll accomplish the same result using bytecode instrumentation.
