// workaround for sun bug on FontMetrics.getAscent()

+ /*
+ * Bug 4399887 has status Closed, not a bug. The comments on the bug
+ * are:
+ * The submitter is incorrectly assuming that the string he has used
+ * is displaying characters which represent those with the maximum
+ * ascent in the font. If (for example) the unicode character
+ * \u00c1 which is the A-acute character used in many European
+ * languages is placed in the bodu of the "Wrong" string it can be
+ * seen that the JDK is exactly correct in its determination of the
+ * ascent of the font.
+ * If the bounds of a particular string are interesting then the
+ * Rectangle FontMetrics.getStringBounds(..) method can be called.
+ * The y value of the rectangle is the offset from the origin
+ * (baseline) apparently needed by the sample test program
+ *
