fix for wrong precedence order

[Haruyuki Kawabe <Haruyuki.Kawabe@unisys.co.jp>]

dava generates wrong Java code (ommiting parentheses) for expressions
that containtwo operations with same precedence such as 2 * (i / 2).
To fix the problem, the comparison of precedence between this and the
subexpression should be <= instead of < in method needsBracketRight().
(See attached diff.)
