Hi,
I oftentimes see the stack trace in a CUBA app that contains the following information for a given random exception that is caused by the UI:
22:12:21.423 ERROR com.haulmont.cuba.web.log.AppLog - Exception in com.haulmont.cuba.web.widgets.CubaButton:

Is there any way to change the output to only talk about the actual exception, not the invocation path from the Vaadin button like this:

I have never used this information from vaadin for anything meaningful. It only causes more noise. In particular, I noticed it when using APM solutions (like the Azure one in the below screenshot):
As the grouping by exception does not do anything meaningful anymore.
Perhaps it is possible to catch those exceptions and then somehow throw away the first exception in the chain. Unfortunately, I was not successful while trying it with extending AbstractUiExceptionHandler. Perhaps someone has already done such a thing, this would be really helpful.
Thanks
Mario
