JTextPane left indent contrast problem

Question

Hi, I'm trying to get left indent to work in a JTextPane - I think it's known as 'hanging indent'.
I got the indent itself to work just fine, however for some reason the indent code changes the contrast of the first rows to much higher than for other rows.
The contrast change seems to happen when I pass a negative float to StyleConstants.setFirstLineIndent(MutableAttributeSet set, float i) and only when anti-aliasing is enabled.
I also tried to 'fix' the contrast by setting:
g2.setRenderingHint(RenderingHints.KEY_TEXT_LCD_CONTRAST, 250) for my JTextPane; 250 is lowest possible contrast value.
This seemed to make the first rows exactly normal, but as excpected, the other rows had way too little contrast now.
Here's a simple example that might demonstrate this 'effect'.
I also noted that when I select the text by dragging it with mouse, the contrast seems to become normal again (I've set the selection color to white in the example code to make this more apparent).
Anyone have ideas what's going on here or how to fix this? Thanks in advance.
I'm using Win XP and JDK 6.0 Update 1, Geforce 7600. My OS has anti-aliasing enabled and Java 6 uses the OS AA setting automatically, so I used -Dawt.useSystemAAFontSettings=false to disable anti-aliasing.

               doc.insertString(
                    doc.getLength(),
                    "When the first line indent is set to a negative value, for some reason the text contrast of first rows will become much higher compared to the other rows.\n",
                         null);
               doc.insertString(
                    doc.getLength(),

Follow-up question:
We have two writers using RH on two different computers. We
work on different FM/RH projects, but we need to use the same
styles. If we use RH's GUI to modify the fmstyles.css styles, do
both writers have to do this separately for their own projects or
is there some way to share the CSS modifications so only one person
has to do it?
