[Java] Invoke static methods without instantiating target object

[mpkorstanje]

Allows glue annotations to be used on static methods. This allows for
example @DataTableType to be used on the type it creates.

public class TestBean {
    private String stringOne;
    private String stringTwo;

    [...]

    @DataTableType
    public static TestBean makeTestBean(Map<String, String> row) {
        return new TestBean(
                row.get("ItemOne"),
                row.get("ItemTwo")
        );
    }
}

Fixes #1950
