Description

I'm taking Netbeans 11 for a spin and now see my project web.xml file has red x in bottom corner of Projects window icon.  Everything seems to work fine despite the validation error.  If I open project in Netbeans 8.2 no issue.  The hover (tooltip) message is: 

 
cvc-elt.1.a: Cannot find the declaration of element 'web-app'
 

If I right click on web.xml file in Projects window and click Validate XML the error is displayed in the Output window along with:

schema_reference.4: Failed to read schema document 'nbres:/org/netbeans/modules/j2ee/ddloaders/catalog/resources/web-app_3_1.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>
