Poor quality font rendering

I need to know what is been tested (the code snippet that created the JFX sample) and native app that produced the other sample.
I think what is going on there is that in JFX we are producing our own subpixel glyphs in the shader (instead using DW to produce subpixel glyph images).
Note the current JDK approach as an a big advantage that we only need to store a single glyph image in the glyph cache's texture.
Using DW to produces subpixel images we will use 3 or 4 times more texture space.
Please, add the screenshot information to https://javafx-jira.kenai.com/browse/RT-14187 so I can look at it.
