Hello, Yes, the stack overflow error is coming from the Java virtual machine and usually the cause is an infinite recursion which is obviously not solved with an increase in the stack size. The rare cases when a larger stack size would be enough cannot be distinguished by the programmer when it is signalled by the JVM so I think the proper place to let the user know is the user manual. We will add a note to the section about XML document validation. Regards, Sorin Syd Bauman wrote:
Now, for my education: where in the documentation should I have looked to find that information? It's pretty important, and so should be pretty obvious. (Best would be to have it in the stack overflow message itself, but I presume that's coming from Java, and you don't have control over it.)
