Yes, it has a quite impressive list of highlighters, also syntax
checking for php and html via plugins
(http://jedit.org/index.php?page=features). I must note however, that
jedit's highlighter configuration is regular-expression based, so it
doesn't have such power that vim or emacs, where you can write code
to highlight. (Actually you could write a plugin that colors
according to more complex rules, as I do in LilyPondTool to make
different background color for Scheme parts.)
Sounds good, but it looks like several hours
work to gain familiarity with it, which I can't
spare just at the moment. Actually, the feature
I miss most is folding, which it has, especially
if it can fold texinfo subsections etc (?),
