[jira] [Updated] (CAMEL-15457) camel-micrometer: NullPonter
exception triggered by EventNotifier
[ https://issues.apache.org/jira/browse/CAMEL-15457?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Espen Andreassen updated CAMEL-15457:
-------------------------------------
Description:
A recent [comit|[https://github.com/apache/camel/pull/3976]] causes NullPointer exceptions in some circumstances, though they are caught and logged as "WARN".
Output from the test testCamelRouteEvents() in MicrometerExchangeEventNotifierTest in master branch:
{noformat}

The problem is that the MicrometerExchangeEventNotifier tries to build/update a metric on inflight exchanges in a route based on an ExchangeEvent with no associated fromRoute/fromRouteId. Events such as "ExchangeSendingEvent", as is created in the test, is an example of such an ExchangeEvent.
