JRE: java version "1.5.0_13"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-b05)
Java HotSpot(TM) Server VM (build 1.5.0_13-b05, mixed mode)
Log4j: release 1.2.15

Remarks:
- the project is a single-thread app (a standalone java program);
- there is only one app running at the same time (and log-files have a unique
name containing a timestamp);
- there is enough free space on the local drive (where the log-files are
written to);
- appenders/log-level settings are not changed during running the app.
