Description
On upgrading from Camel 4.8.0 to 4.8.1, the app is resulting in application startup failure. The root cause is a conflict between two beans: applicationTaskExecutor and taskScheduler, both of which are being detected by org.apache.camel.component.platform.http.springboot.SpringBootPlatformHttpAutoConfiguration.
Removing the @EnableScheduling fixes is as there will no longer be two Executor Beans. However, this will result in us not being able to use Spring scheduler.
Below is the Log:

Description:
Field executor in org.apache.camel.component.platform.http.springboot.SpringBootPlatformHttpAutoConfiguration required a single bean, but 2 were found:
- applicationTaskExecutor: defined by method 'applicationTaskExecutor' in class path resource [org/springframework/boot/autoconfigure/task/TaskExecutorConfigurations$TaskExecutorConfiguration.class]
- taskScheduler: defined by method 'taskScheduler' in class path resource [org/springframework/boot/autoconfigure/task/TaskSchedulingConfigurations$TaskSchedulerConfiguration.class]
This may be due to missing parameter name information
Action:
Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed
Ensure that your compiler is configured to use the '-parameters' flag.
You may need to update both your build tool settings as well as your IDE.
