We are in the process of switching from Wildfly26 to Wildfly27.
We have made the changeover to Jakarta EE 10. When starting Wildfly27, an error occurs under Wildfly 26, the service worked without problems.
When starting the MBean /SAR, the error occurs:

 

Caused by: java.lang.RuntimeException: Provider for jakarta.activation.spi.MailcapRegistryProvider cannot be found.
