Access denied on Windows7 64bit

[Oti]

Hi all,

recently I joined the AdoptOpenJDK program and started to test the new
build on Windows.
You can find a list what I did here:
http://java.net/projects/adoptopenjdk/pages/BuildWindows.

The disabling of ASLR really helped: Before that I got a never ending
hotspot build with 0% CPU load.
Now hotspot builds just fine, thanks for the tip in
http://mail.openjdk.java.net/pipermail/build-dev/2012-February/005594.html!

What I am stuck with now is an Access denied stack trace.
I can reproduce it as many times I want, like this:

Interestingly, it is always the same background.gif which appears in the
error message.
>From the above mentioned mail thread I guess that this could have something
to to with Security Software (Anti-Virus, ...)
I use Microsoft Security Essentials and
 - disabled all real time access
 - excluded the whole jdk folder
 - excluded the whole cygwin folder
, but without any effect.

Hopefully somebody on this list has a tip what I could try next.

Thanks in advance, and best wishes,
Oti.

I am running a VM inside VMware Fusion on a Macbook Air
