#1258 Java 8 Lambda parse error on direct field access

[janScheible]

PMD is able to parse a Lambda like this without any problems:

object.event = () -> {
    Request request = new Request();
    request.setId(42);
};

Whilst this Lambda leads to an error:

object.event = () -> {
    Request request = new Request();
    request.id = 42;
};

The error is reported as:

net.sourceforge.pmd.lang.java.ast.ParseException: Encountered " "(" "( "" at line 148, column 40.
