There are many bug reports about the fact that Properties.list truncates values larger than 40 characters to 37 characters + "...". This cannot be changed for compatibility reasons. Fair enough. However, we should at least document that behavior in the API.

Actually the API don't tell you about it:

    /**
     * Prints this property list out to the specified output stream.
     * This method is useful for debugging.
     *
     * @param out an output stream.
     */
    public void list(PrintStream out) {

and
    /**
     * Prints this property list out to the specified output stream.
     * This method is useful for debugging.
     *
     * @param out an output stream.
     * @since JDK1.1
     */
     public void list(PrintWriter out) {
