Tomcat 9.0 Failed to Load DSpace Backend

[Zhongping Yan]

I used to build DSpace backend with jdk 11.0.11 and worked well with Tomcat 9.0. Last weekend I updated JDK to jdk 11.0.12 and rebuilt DSpace backend. Following the instructions, DSpace backend was built and installed successfully. When starting Tomcat, it always failed to load the backend with errors as below: 

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'openSearchController' defined in file [C:\Tools\dspace\webapps\server\WEB-INF\classes\org\dspace\app\rest\OpenSearchController.class]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.dspace.app.rest.OpenSearchController]: Constructor threw exception; nested exception is java.lang.Error: Unresolved compilation problems: 

The package javax.xml.transform is accessible from more than one module: <unnamed>, java.xml

The package javax.xml.transform.stream is accessible from more than one module: <unnamed>, java.xml

The package org.w3c.dom is accessible from more than one module: <unnamed>, java.xml

Document cannot be resolved to a type

Then I uninstalled jdk 11.0.12, installed jdk 11.0.11, and re-built DSpace backend. Tomcat still cannot load the backend with same problem.

More log messages from Tomcat log file catalina.2021-09-28.log are as below:

Any suggestions?
