[#9076] - Fixed linespacing size does not work as needed

If I have a text field with a multi lined text inside.

<staticText>
<reportElement x="0" y="0" width="198" height="252"/>
<textElement textAlignment="Left" verticalAlignment="Top" markup="none">
<font fontName="GostAproe" size="12"/>
<paragraph lineSpacing="Fixed" lineSpacingSize="14.0"/>
</textElement>
<text><![CDATA[line 1
line 2
line 3
...
]]></text>
</staticText>

It renders a text line like 14.0 + maxDescent

See attached screenshot

An error is in AbstractTextRenderer.class. maxDescent value adds in any way not relative to the selected LineSpacing.
