[slf4j-user] varargs

[Ceki Gülcü]

Zohar, Martin,

I've just done a compatibility review. Changing the Logger interface
from

public interface Logger {
  public void debug(String msg);
  public void debug(String format, Object arg);
  public void debug(String format, Object arg1, Object arg2);
  public void debug(String format, Object[] argArray);
}

to:

public interface Logger {
  public void debug(String msg);
  public void debug(String format, Object arg);
  public void debug(String format, Object arg1, Object arg2);
  public void debug(String format, Object...);
}

The second form requires JDK 1.5.

The second form still yields good performance for the common
cases with 0,1 and 2 args. Most importantly. clients compiled against
the 1st (JDK14) version would continue to run as in the presence of
the second interface (JDK15).

At present time, I'd like to release 1.1 without any more significant
changes. If existing users do not object, in the next SLF4J release, namely
1.2, we could bump the JDK requirement to 1.5 instead of 1.4.

How does that sound?
