I can, although I'm now pretty convinced it's not an XML Beans issue.
The fact is the default stack size must be smaller for 32bit jse6, and
long, complex patterns require a lot of stack.

Hi Chris,
Thanks for finding an investigating an issue like this.
Can I get you to file a jira issue to track this?
Thanks,

After looking further into this issue, in java6 the default stack size
is not different between Linux and Windows but between 32bit and 64bit
implementations. This explains a lot as we're using 64bit linux.
I can't find what the default stack sizes were in java5 though. I
guess
I'll just have to add a -Xss parameter to my application although this
doesn't fill me with confidence,
"Options that begin with -X are non-standard (not guaranteed to be
supported on all VM implementations), and are subject to change without
notice in subsequent releases of the JDK." -
