--------------------------------------------

   Assignee: Michael Glavassevich  (was: Xerces-J Developers Mailing List)

> Poor performance when processing schemas with high values of maxOccurs

>                 Key: XERCESJ-773
>                 URL: https://issues.apache.org/jira/browse/XERCESJ-773
>             Project: Xerces2-J
>          Issue Type: Bug
>          Components: XML Schema Structures
>    Affects Versions: 2.5.0
>         Environment: Operating System: Linux
> Platform: PC
>            Reporter: Steve Baker
>         Assigned To: Michael Glavassevich
>
> When validating an instance of an XML order against its schema, the process
took
>  5 minutes 7 seconds and required an increased maximum heap size to run to
> completion.
> The problem was traced to a maxOccurs value of 9999 on an element (the
> OrderLine). Changing this to unbounded reduced the time taked to 1.16 seconds
> and required no increase in the default heap size.
