Description

Hello everyone,

Unfortunately when I’m testing a route containing a micrometer endpoint on Camel 3.20.1 using Spring Boot, then I’m getting a

java.lang.NullPointerException: null
        at org.apache.camel.component.micrometer.eventnotifier.MicrometerExchangeEventNotifierNamingStrategy.getTags(MicrometerExchangeEventNotifierNamingStrategy.java:53)
        at org.apache.camel.component.micrometer.eventnotifier.MicrometerExchangeEventNotifier.handleDoneEvent(MicrometerExchangeEventNotifier.java:105)
       at org.apache.camel.component.micrometer.eventnotifier.MicrometerExchangeEventNotifier.notify(MicrometerExchangeEventNotifier.java:75)
        […]

 

The exception only occurs in case I’m using:

producer.send(ExchangeBuilder.anExchange(context).withBody("hello").build());

It’s working fine in case of

producer.sendBody(“hello”);

For both statements, in 3.18.3 it’s working fine – in any case, meaning in 3.18.3 and 3.20.1, the ExchangeBuilder.anExchange(context).withBody("hello").build().getEndpointFrom() is null, however, only in 3.20.1 it looks like that getEndpointFrom() indirectly causes the NPE in line 53.

Pls. find a repo case attached.repro.zip
