/**
 * Platform logger provides an API for the JRE components to log
 * messages.
 *
 * The PlatformLoggerBridge interface is implemented by the System.Logger
 * objects returned by our default JUL provider - so that JRE classes using
 * PlatformLogger see no difference when JUL is the actual backend.
 *
 * The recommendation for JRE classes going forward is to use
 * java.lang.System.getLogger(String name), which will
 * use Lazy Loggers when possible and necessary.
 *
 * PlatformLogger is now only a thin adaptation layer over the same
 * loggers than returned by java.lang.System.getLogger(String name).
