Re: SEVERE - Can't initialize Metrics Registrar

Hi,

I've created a simple testcase which creates a war file which when 
deployed for a second time with a different name generates the error

https://github.com/semanticfire/tomee-test

Take a Tomee Plus 9.1.0 and copy test.war to webapps/test1.war and 
webapps/test2.war

The deployment of test2.war will result in the error.

Hi,

Looking at the source code where this error comes from it seems it is 
related to Tomee Microprofile.

The error occurs when multiple apps are deployed, I have not been able yet 

to find what attributes the apps need to have to casue this error.

Hi,

When deploying an app on Tomee 9.1.1 I get the following error on the 
console:


SEVERE - Can't initialize Metrics Registrar: SRMET00009: Gauge with id 
MetricID{name='classloader.loadedClasses.count', tags=[]} already exists

The app is a war which contains a MessageDriven class
I'm not using any of the metrics etc, nor can I find information about 
this error.

The app works without any issues.

Thanks in advance,
