When TomEE is starting, I see this warning:
WARNING [http-nio-80-exec-18] org.apache.batchee.container.services.ServicesManager.init You didn't specify org.apache.batchee.jmx.application and JMX is already registered, skipping
What does it mean?
By default, Apache BatchEE (bundled with TomEE) activates a JMX facade for JobOperator via org.apache.batchee.jmx (boolean). According to the official documentation, the property org.apache.batchee.jmx.application is used to specify
a name to distinguish job operator between applications when batchee is not shared (will be shown in JMX name)
On startup, BatchEE tries to register itself on the platform's mbean server. To do so, it relies on the app's name given via org.apache.batchee.jmx.application. In case this property is not set, a default value is used. In case, the JMX facade is already registered with this default name, the log message mentioned above is printed.
If BatchEE is available in TomEE's classpath, this initalization is triggered via the BatchEEServiceManager during startup and the property openejb.batchee.integration.skip is not true.
If you do not need JMX monitoring on BatchEE, you can either disable the integration via openejb.batchee.integration.skip=true or via org.apache.batchee.jmx=false.
