XWiki infinispan InstanceAlreadyExistsException

$

Hi,

My XWiki Server restarted yesterday and has seemingly updated the JDK to the latest GA version shipped with CentOS9.

Following this, my XWiki server (Tomcat Servlet) will not start and throws a 500 error when trying to access.

I suspected this might be due to an older version of XWiki I was running so I followed the WAR upgrade path and have added the latest stable version.

The error is still the same after this.

In the catalina.out log it seems to all go down too:

Caused by: javax.management.InstanceAlreadyExistsException: org.xwiki.infinispan:type=CacheManager,name="xwiki",component=CacheManager
	at java.management/com.sun.jmx.mbeanserver.Repository.addMBean(Repository.java:322)

I have tried changing the domain within WEB-INF/cache/infinispan/config.xml
I have also tried increasing the cache size to 50k.
But this still gives the same errors.

I have only got a single xwiki folder within the tomcat webapps folder.

I have attached the Catalina.out from today for the latest single full statup sequence.

Hopefully someone can help. Thanks!
