jasper2 doesn't support the "validateXml" attribute

[Gernot]

Hi,

I did an upgrade from tomcat 7.0.29 to 7.0.50.
In 7.0.50 jasper2 ant task quits with error 'jasper2 doesn't support the
"validateXml" attribute'

Here's the mentioned code:
    <jasper2 validateXml="false"
             uriroot="${build}"
             webXmlFragment="${build}/WEB-INF/generated_web.xml"
             addWebXmlMappings="true"
             outputDir="${build}/WEB-INF/classes"
             compilerSourceVM="7.0"
             compilerTargetVM="7.0" />


I havn't found any information about this in tomcat's changelog.
Is this a bug? Or a feature?
What's the suggested way to handle this error?

Thanks
