The output such as: 06:16:37,297 ERROR [STDERR] Debug: /accountList If you look at the code, it writes logging text to stderr, which shows up as a error output when it is trapped by log4j. This is pretty lame, if you ask me, but I think the code's authors (Sun Microsystems) did not want to include any third-party libraries like log4j due to licensing issues.
