The reason seem to be (but I haven't been able to confirm as I have been busy
in other matters)
that the Task has a default constructor (that I use). To use the 'log()'
method, I'd need to
invoke a constructor with the node name I want to use.
Smthg like :
<snip>
class MyTask extends Task
{
public MyTask()
{
super("com.cpy_name.pckg.MyTask");
}
...
}
</snip>
If that is the case, the constructor could use the following definition :
logger = Logger.getLogger(this.getClass());

Any fool can write code that a computer can understand.
Good programmers write code that humans can understand.
