FULL PRODUCT VERSION :
java version "1.4.2_05"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_05-b04)
Java HotSpot(TM) Client VM (build 1.4.2_05-b04, mixed mode)


ADDITIONAL OS VERSION INFORMATION :
Windows 98 Second Edition

A DESCRIPTION OF THE PROBLEM :
The Properties.list() method methods truncates properties which are longer than 40 characters and appends them with an ellipses.
The external directories (java.ext.dirs), library directories (java.library.paths), and other properties which are critical runtime properties which specify path information are all truncated.

 The documentation for the two list() methods says the methods are "useful for debugging", but incomplete information is not useful for debugging.

The source for the list methods in /java/util/Properties.java contains an "if" clause that makes the decision to truncate property values longer than 40 characters. Also, an internal enumerator class is used.

I used the following code to correctly display the properties instead of using list():

        Properties props = System.getProperties();
        //props.list(System.out);
        for (Enumeration k = props.keys() ; k.hasMoreElements() ;) {
            for (Enumeration e = props.elements() ; e.hasMoreElements() ;) {
                System.out.println(k.nextElement() + " = " + e.nextElement());
            }
        }
