#55 null in expression with conditional

[David Tramer]

When using Expression Evaluator to evaluate:

null==null && "OIUO"!="edede"

I get:

net.janino.Java$CompileException: Line 1, Column 5:
Cannot compare "null" with primitive type "void"

Man... that was a subtle one! Generally, JANINO does not
attempt to compile constant expressions like "null==null"
into code, because it recognizes them as constant.
Only in this case (an && expression with the LHS being a
constantly false expression) it does so, and fails.
"BinaryOperation.compileBoolean()" now checks whether "this"
has a constant value.
Will release in V 2.0.9.
