Spencer Stecko created XERCESJ-1734:
---------------------------------------
Summary: Xerces does not correctly interpret negative jaxp
processing limits as "NO LIMIT"
Key: XERCESJ-1734
URL: https://issues.apache.org/jira/browse/XERCESJ-1734
Project: Xerces2-J
Issue Type: Bug
Components: XML Schema API
Affects Versions: 2.12.1
Reporter: Spencer Stecko
According to the oracle documentation, many of the limits to jaxp processing
settings can be set to zero or a number less than zero to indicate no limit:
[https://docs.oracle.com/javase/tutorial/jaxp/limits/limits.html]
However, when I do this (with jdk.xml.maxOccurLimit), I get the following stack
trace:
{code:java}
Caused by: org.xml.sax.SAXParseException: Current configuration of the parser
doesn't allow the expansion of a content model for a complex type to contain
more than -1 nodes.

I have no idea what this repo I found is, but it appears to include some sort
of mirror of the apache xerces codebase, and the bug is clearly visible here:
