[cp-patches] FYI: fix for java.awt.FontMetrics

[Roman Kennke]

There was a bug in FontMetrics.charsWidth. This method iterated from 
offset to len, which is only ok in the case when offset == 0. In all 
other cases this yields false results. It should of course iterate from 
offset to offset + len. This is fixed.

        * java/awt/FontMetrics.java
        (charsWidth): Iterate to len + offset instead to len.
