simple names with parenthesis around get recognized as CastExpr

[GoogleCodeExporter]

this kind of expression shouldn't be parsed to CastExpr

I see currently no way to do that easily in the parser without a complete 
semantic
analysis. Tell me if I'm wrong. If you point me into the right direction I'm 
willing
to do the needed coding to implement it correctly in javaparser.

I haven't found a way to determine this kind of expression in the parser.
There is no syntax difference between
  int a = (foo)+bar;
and
  byte a = (byte)+bar;
where the second expression is indeed a CastExpr. Semantics should be used to
determine if it is a Cast or not. But, if the expression looks like this:
int a = (+foo)+bar;
the parser will recognize it as a simple BinaryExpr with parenthesis in the 
left operand.

What I think you could do is add a specific semantic for this case in your 
visitor.
It will isn't be a simple task, I will research a little more to check if there 
is
any other solution, if I find anything I will reopen this issue.

I have found a way to solve this issue in the Java Language Specification. But 
to
solve this I will need to make a lot of changes in the parser, I have starter 
the
changes now.
