Description ChristophK CLA 2011-05-05 10:43:08 EDT 
Build Identifier: 20110301-1815

After upgrading my Internet Explorer to version 9, I can no longer use BrowserFunctions within a SWT Browser that return an Object array. When I do, the jvm crashes with the message:
    EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x000007fef783a2fb, pid=1208, tid=4048
and claims the problematic frame is "jscript9.dll+0xa2fb"

I also built a small test case and tried it with the SWT nightly build (swt-N20110503-2000-win32-win32-x86_64), which resulted in the same problem.

I used the 64-bit version and the Hotspot JRE 1.6.0_23-b05, if that makes any difference.

The crash seems to happen in this line:
    int rc = arrayTypeDispatch.QueryInterface (COM.IIDIDispatchEx, result);
of the method 
    Variant convertToJS (Object value)
of the class
    org.eclipse.swt.browser.WebSite

Reproducible: Always

Steps to Reproduce:
1. Create a BrowserFunction that returns an Object[]-Array in its execute-method
2. Call the function in html-code within a swt browser
3. watch it crash
