Setting the Java thread stack size

Hi experts,

I was just browsing thru a customers BI 4 landascape and I found out, that for some customized (copied) APS services the Java thread stack size isn't set to any value. Default APS shows -Xss1M, this value isn't set (even exists) on any copied APS.

Is that by design, or has this value to be set afterwards at all time?

cheers,

Sasha
