Hi everyone,
I'm working with FOP embedded in a Java project. During a transformation of
an XML file I get the following exception:
java.lang.StackOverflowError

Seems like Xalan is doing a lot of recursive calls and the stack memory
overflows. Is there any way to overcome this problem?
Thanks in advance.
