Build Identifier: Helios

Please consider this snippet

Browser browser = new Browser (shell, SWT.NONE); // Uses Mozilla on Linux, WebKit on OSX and IE on Win
System.out.println(browser.evaluate("return 2+2;");

it returns 4 on both Linux and OSX (any arch with SWT 3.6.1), but NULL on Win7 (I only tested on 32bit version with SWT 3.6.1)

Reproducible: Always

I've found where the problem is... it behaves the same in XP with SWT 3.5.
You've to set an url before calling the evaluate method:

browser.setUrl("about:blank");
System.out.println(browser.evaluate("return 2;")); // prints 2.0

I'm not sure it is actually a bug, however it behaves differently from Mozilla or WebKit. But I guess it's IE not SWT.
