ClearCase update fails with NullPointerException

Update fails because update command uses changelog command without setting logger on it - so
changelog command fails with NullPointerException at the beggining of execution in:
getLogger().debug( "executing changelog command..." );

The required change is in
ClearCaseUpdateCommand.java:
protected ChangeLogCommand getChangeLogCommand()

{ return new ClearCaseChangeLogCommand(); }

should be:
protected ChangeLogCommand getChangeLogCommand()

{ ClearCaseChangeLogCommand c= new ClearCaseChangeLogCommand(); c.setLogger(getLogger()); return c; }

This change is done according to convention used in cvs,perforce,starteam providers when invoking one command from another.
