Perhaps.  I'll admit I've never seen this problem before.  Don't ask
me about Perl syntax highlighting unless you're ready for a rant,
though.

Does it actually say `blah'?  I see your .emacs talks about setting
debug on error; perhaps it'd be a good idea to get a backtrace?  (M-x
toggle-debug-on-error should set that.)

This is what the documentation for the relevant variable says (note
I'm using emacs21, which may be slightly different):

} max-lisp-eval-depth's value is
} 300
} 
} Documentation:
} *Limit on depth in `eval', `apply' and `funcall' before error.
} This limit is to catch infinite recursions for you before they cause
} actual stack overflow in C, which would be fatal for Emacs.
} You can safely make it considerably larger than its default value,
} if that proves inconveniently small.
} 
} You can customize this variable.

You're not running this on NT, are you?  Or running XEmacs?  (I only
insult you by asking because the only mentions of your error message
I've been able to find talk about NTEmacs or XEmacs.)

Here goes.  (If I'm not helpful, try comp.emacs or the comp.emacs.*
hierarchy.)

This looks pretty suss.  My copy of emacs sez:

} font-lock-maximum-decoration's value is
} t
} 
} Documentation:
} *Maximum decoration level for fontification.
} If nil, use the default decoration (typically the minimum available).
} If t, use the maximum decoration available.
} If a number, use that level of decoration (or if not available the maximum).
} If a list, each element should be a cons pair of the form (MAJOR-MODE . LEVEL),
} where MAJOR-MODE is a symbol or t (meaning the default).  For example:
}  ((c-mode . t) (c++-mode . 2) (t . 1))
} means use the maximum decoration available for buffers in C mode,
} level 2
} decoration for buffers in C++ mode, and level 1 decoration otherwise.
} 
} You can customize this variable.
} 
} Defined in `font-lock'.

(To see this documentation for a variable, use C-h v <varname>.  The
customize interface (click on the work `customize') is fairly obvious,
but probably more than you feel like getting into right now.)

What happens if you set this to t instead?  That looks like it will
then not load the jde mode until needed.  I can't see it helping,
though.

Also try commenting out all the font-lock stuff in your .emacs and
turning on font-lock by hand after editing a .java file:

M-x font-lock-mode
