[jira] Commented: (XMLBEANS-52) Validator loops when schema has certain conditions
[ http://nagoya.apache.org/jira/browse/XMLBEANS-52?page=comments#action_54941 ]
Fernando Dobladez commented on XMLBEANS-52:
-------------------------------------------
We are experiencing the same problem here.
For some XMLs, the validate() method never returns (or takes way too long, minutes) and was consumming all the CPU.
As the bug reporter suggested, we removed the "unbounded collection of unbounded elements" that we were using, and the problem disappeared.
We are using the binary distribution of 1.0.3.

> When the following schema is used to generate XmlBeans, and a valid file is validated using the XmlObject.validate(), then it loops. After 2 to 10 minuts it returns. I claims 100% cpu usage while it loops.
> Here are the schema:
> <?xml version="1.0"?>
> <xsd:schema targetNamespace="http://pfa.dk/dummy/errorInXmlBeansValidation.xsd" xmlns:tns="http://pfa.dk/dummy/errorInXmlBeansValidation.xsd" xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
> <!-- this schema is valid, but the XmlBeans validation can't handle an unbounded collection of unbounded elements. -->
> <xsd:element name="aList" type="tns:MyList"/>
> <xsd:complexType name="MyList">
> <xsd:sequence maxOccurs="unbounded">
> <xsd:element name="myListEntry" type="tns:ListEntry" minOccurs="0"/>
> </xsd:sequence>
> </xsd:complexType>
> <xsd:complexType name="ListEntry">
> <xsd:sequence>
> <xsd:element name="HelloWorld" type="xsd:string" minOccurs="0"/>
> </xsd:sequence>
> </xsd:complexType>
> </xsd:schema>
> and here is a simple xml file:
> <?xml version="1.0" encoding="UTF-8"?>
> <!--Sample XML file generated by XMLSPY v5 rel. 4 U (http://www.xmlspy.com)-->
> <aList xmlns="http://pfa.dk/dummy/errorInXmlBeansValidation.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://pfa.dk/dummy/errorInXmlBeansValidation.xsd
> C:\pfa\techr3\TransformationWorkbench\schema\errorInXmlBeansValidation.xsd">
> <myListEntry>
> <HelloWorld>Hello World</HelloWorld>
> </myListEntry>
> </aList>
> I can send you a working java project, which shows the bug.
