Category Manager error

bubaucsal — Tue, 06 Aug 2024 14:42:15 GMT

I'm having problems listing categories within alfresco, the following error message appears.
"JavaException: java.lang.IllegalArgumentException: methods with same signature reversed() but incompatible return types: [interface java.util.List, interface java.util.Deque]".
I would like to know what could be happening and how I resolve it. My alfresco is on version 7.3.1.

What Java version are you using? 17 or 11 are recommended.

Hi Angle,

I'm using jdk-21 and I get the same only when I use chemistry-opencmis-client-impl

Exception in thread "main" org.apache.chemistry.opencmis.commons.exceptions.CmisRuntimeException: methods with same signature reversed() but incompatible return types: [interface java.util.List, interface java.util.Deque]

I start tomcat-alfresco with java 21 and it works and I dont seen any error, when I use share app.

How to deal with that? I will try to now jdk 17

Also I see no code in Alfresco related to the category manager calling any operation called "reversed". So I wonder where that conflict might arise. A more extensive stacktrace would be required to understand that.
