Log throwing an exception.
<p>
Use to log that a method is terminating by throwing an exception. The logging is done using the
<code>finer</code> level.
<p>
This is a convenience method that could be done instead by calling
{@link #finer(String, Throwable)}. The string message will start with <code>"THROW"</code> and
include the class and method names.

@param sourceClass Name of class that issued the logging request.
@param sourceMethod Name of the method that issued the logging request.
@param thrown The Throwable that is being thrown.
