> *Description:*
> We have identified a behavior in Apache Camel that does not match the
> expected error propagation when using consumers with
> {{bridgeErrorHandler=true}} and an error handler configured with
> {{{}handled=false{}}}.
> *Problem:*
> When an error occurs in a consumer, the error is sent to the configured error
> handler. If the error handler sets {{{}handled=false{}}}, the exchange *does
> not continue to a subroute* for further processing, unlike other error
> scenarios.
> *Impact:*
> * The exchange is marked as failed (correct), but processing stops before
> reaching configured subroutes.
> * This breaks reuse of subroutes for error handling logic and affects
> integration flows where error handling needs to occur in a centralized
> subroute while keeping the exchange in a failed state.
> *Steps to Reproduce:*
> We created four use cases:
> *Use Case 1 – Error during exchange ({color:#00875a}working{color})*
> # Error occurs in route 2.
> # Error is sent to error handler with {{{}handled=false{}}}.
> # Error is sent further to subroute.
> !image-2026-01-26-15-07-43-377.png!
> *Use Case 2 – Error in consumer with bridgeErrorHandler=false
> ({color:#00875a}working{color})*
> # Error occurs in consumer.
> # Error is *not* sent to error handler.
> !image-2026-01-26-15-08-06-642.png!
> *Use Case 3 – Error in consumer with bridgeErrorHandler=true / handled=true
> ({color:#00875a}working{color})*
> # Error occurs in consumer.
> # Error is sent to error handler with {{{}handled=true{}}}.
> # Error is sent to subroute.
> !image-2026-01-26-15-08-13-916.png!
> *Use Case 4 – Error in consumer with bridgeErrorHandler=true / handled=false
> ({color:#de350b}not working{color})*
> # Error occurs in consumer.
> # Error is sent to error handler with {{{}handled=false{}}}.
> # *Error is not sent to subroute* (unexpected).
> !image-2026-01-26-15-08-20-169.png!
> *Expected Behavior:*
> * In Use Case 4, the exchange should reach the subroute, similar to Use Case
> 1, while keeping the exchange in a failed state.
> !image-2026-01-26-15-08-26-808.png!
> *Observed Behavior:*
> * Exchange does not continue to the subroute.
> * Exchange remains in failed state but bypasses the subroute.
