Subject: [PATCH] Use Log4j IOStreams to redirect System.out/err to logger
Log4j2 provides an optimized implementation of PrintStream that
redirects its output to a logger. Use it instead of a custom
implementation for minor performance improvements and some fixes.
With the old implementation, each call to System.print()
results in a separate line, even though it should not result in
a line break. Log4j's implementation handles it correctly.
