[jira] [Updated] (BATIK-1149) CSSLexicalUnit.getIntegerValue throws

RGB color values are supported in all major browsers.
An RGB color value is specified with: rgb(red, green, blue). Each parameter (red, green, and blue) defines the intensity of the color and can be an integer between 0 and 255 or a percentage value (from 0% to 100%).
For example, the rgb(0,0,255) value is rendered as blue, because the blue parameter is set to its highest value (255) and the others are set to 0.
Also, the following values define equal color: rgb(0,0,255) and rgb(0%,0%,100%).
{quote}.
In batik-css-1.7 and 1.8, the CSSLexicalUnit.getIntegerValue method throws an IllegalStateException when defining the rgb value using percentages. Example code below:
{code}
<span style="color: rgb(10%,10%,80%)">foo</span>
{code}
