Description

Hi All,

We are trying to migrate from version 5.15.11 on 5.16.0.

And we have faced with an error with loading the activemq.xml:

2020-10-28 20:27:13,271 | ERROR | Failed to load: class path resource [activemq.xml], reason: Line 126 in XML document from class path resource [activemq.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 126; columnNumber: 163; cvc-complex-type.3.2.2: Attribute 'allowLinkStealing' is not allowed to appear in element 'transportConnector'. | org.apache.activemq.xbean.XBeanBrokerFactory | main
org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 126 in XML document from class path resource [activemq.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 126; columnNumber: 163; cvc-complex-type.3.2.2: Attribute 'allowLinkStealing' is not allowed to appear in element 'transportConnector'.

As I can see the problem is that we are using XML validation with referring on generic XSD, like this:

<beans
 xmlns="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
 http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core.xsd">

And allowLinkStealing attribute is absent in the new versions of the XSD (generic and activemq-core-5.16.0.xsd).

While allowLinkStealing property is still available for Transport configuration why it was excluded from XSD?
