[xep-support] Re: FW: [renderx #22766] unstable validation errors in Win7/2008 @ x64 JRE

I got a laugh about this:

> Please note that Java 6.0.23 and earlier have security vulnerabilities and
shouldn't be used in production:

I would add this:

Please note that Java 6.0.23 and *later* has bugs and may not work for you.

errors in Win7/2008 @ x64 JRE

Hi,

Interesting. I can confirm that, when running xep through ant:

* I get the validation error with 64-bit Java (build 1.6.0_23-b05)

* No error with 64-bit Java (build 1.6.0_20-b02).

* No error with 32-bit Java (build 1.6.0_24-b07)

So yes, there seems to be an issue with 64-bit Java (ant is using the JDK
version, obviously, but I don't think that should make a difference?) as you
pointed out.

Please note that Java 6.0.23 and earlier have security vulnerabilities and
shouldn't be used in production:

Cheers,
