Chris,
>From my experience, any Java project once it gets complex starts having
to use some -X option (and all JVMs support them), so I wouldn't be too
worried about that.

Windows Java 1.6.0_03
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

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." -
