----------------------------------------
Summary: Xerces crashes when validating an XML with an XSD that
contains asserts
Key: XERCESJ-1633
URL: https://issues.apache.org/jira/browse/XERCESJ-1633
Project: Xerces2-J
Issue Type: Bug
Components: XML Schema 1.1 Structures
Affects Versions: 2.11.0
Reporter: Octavian Nadolu
Attachments: assert.xsd, dashboard.xml
One of Oxygen users reported us a crash, If you validate "dashboard.xml" with
"assert.xsd" schema.
A NullPointerException is thrown in the XPath2 library, when the assert xpath
expression is evaluated. This exception is cached in
"org.eclipse.wst.xml.xpath2.processor.internal.function.FsEq" class,
"do_cmp_value_op()" method at line 381.
The problem is that there is a System.exit(1) in that method, and after the
exception is printed in output, the System.exit is called.
I looked in the sources of the XPath2 library and the problem was fixed in the
last build of the XPath2 library, but Xerxes used an older version of the
library (1.2.0). Maybe you can try to rebuild the XPath2 library and remove the
System.exit.
I tested on the xml-schema-1.1-dev branch.
