This is same rfe as 4593198, except this is for Solaris platforms:

In case when the logical font (e.g. dialog) is used in applications or applets, the rendered characters are too small to read.

We now use Lucida font in in font.properties.th on Windows platforms, we should make it consistent on Solaris platforms. Please see the attachment for comparison, the golden image on the right hand side is with Lucida font, the image on the left hand side is with logical font in th_TH locale.
