Roger updated CAMEL-11215:
--------------------------
Description:
My processor in the router throws an exception but the Kafka component still
commits the offsets.
My route: (heavily redacted and modified)
{code:title=Route|borderStyle=solid}
from( "kafka://blah-blah" ).routeId("MyRoute")
.convertBodyTo( MyData.class )
.process( "MyProcessor" )
.to( "DestinationProcessor" );
{code}
The exception I get:

Here is the corresponding Kafka component code:(KafkaConsumer.java) -This part
of the code does not seem to handle the exception. The exception handler simply
eats up the exception and the fall through code happily commits the offsets. Is
this a bug? or am I missing something?
