See GlyphCache#addDataToQuad(), in the isLCDCache case,
dx1 = Math.round(dx1 * 3.0f) / 3.0f;

Later in /graphics/src/main/jsl-prism/PaintTextureSecondPassLCD.jsl
that dx1 (which was rounded to .0, 0.33, 0.66) is used to offset the pixel 
color RGB values to produce the sub pixel image.

Rounding that dx1 to pixel (like GlyphCache does for grayscale text), then I 
would expected -Djavafx.text=t2k and SWT to look very similar.
