logger not declared lead to NPE

[sirnono]

below logger.debug line can lead to NPE if logger declaration not reached.
First initialize the logger or use System.out.

From Main.java

    private static Logger logger = null;

public static void main(String... args) {
	int resultValue = 0;
	try {
		resultValue = mainInternal(args);
	} catch (Exception e) {
		System.err.println("We got an exception on merge: " + StringUtils.join(args, " "));
		e.printStackTrace();
		System.exit(1);
	}
	logger.debug("Exiting with exit code {}", resultValue);
	System.exit(resultValue);
}

Sorry for fixing it so late. Fixed it with the 1.7.0.
