As an AI language model, I can explain that this error message is related to XML schema validation. It indicates that while parsing an XML document, the XML schema validator encountered an element or attribute with a data type of "int" but the value provided for that element or attribute was an instance of the Java class "java.util.ArrayList," which is not compatible with the "int" data type.
To fix this error, you should check the XML document to ensure that the values provided for all "int" elements and attributes are valid integers and not instances of other Java classes. Alternatively, you may need to modify the XML schema to allow for the use of "java.util.ArrayList" as a valid data type for the affected elements or attributes.
