This was made for JDBC connections, as they often initialize prior to the tracing component.</p><p>The most recent tracing component instantiated is available through <code class="literal">Tracing.current()</code>.
You can also use <code class="literal">Tracing.currentTracer()</code> to get only the tracer.
If you use either of these methods, do not cache the result.
