You can determin class loading by looking at the uses of Class and 
Class.forName() etc.

If you remove Log.java and its dependent classes,  most of the IO related 
stuff would disappear.

How could I determine where, in the code, are located the methods that
are doing optional class loading.

For information the BigInteger & BigDecimal can be taken for the first
one at: http://www.bouncycastle.org/ and for the second one:
http://www2.hursley.ibm.com/decimalj/.

The rest of the problem deal with classes that belong to the java.io
package.

In fact the main problem is that I'm unable to see how the things are
working together. I tried to obtain an UML schema from the sources but
the soft crash duting the parsing the files.

I hope, I'm not too anoying with all my questions.
