/**
 * Utility class only for sjavac logging.
 *
 * Logging in sjavac has special requirements when running in server/client
 * mode. Most of the log messages is generated server-side, but the server
 * is typically spawned by the client in the background, so the user usually
 * does not see the server stdout/stderr. For this reason log messages needs
 * to relayed back to the client that performed the request that generated the
 * log message. To support this use case this class maintains a per-thread log
 * instance so that each connected client can have its own instance that
 * relays messages back to the requesting client.
 *
 * On the client-side (or when running sjavac without server-mode) there will
 * typically just be one Log instance.
 *
 *  <p><b>This is NOT part of any supported API.
 *  If you write code that depends on this, you do so at your own risk.
 *  This code and its internal interfaces are subject to change or
 *  deletion without notice.</b>
