Reactive Executor Tomcat

Since Camel 3.17

Deprecated since Camel 4.22

This component is deprecated and will be removed in a future release. Use the default ReactiveExecutor (built into camel-core ) instead.

The camel-reactive-executor-tomcat was intended for users of Apache Tomcat, to let Camel applications shutdown cleanly when being un-deployed in Apache Tomcat.

The cross-thread ThreadLocal cleanup that distinguished this component from the default ReactiveExecutor relied on reflective access to the private Thread.threadLocals field. This approach is denied by the JDK module system since JDK 17 and is incompatible with virtual threads. Without that cleanup, this executor is functionally identical to the default.

To migrate, simply remove the camel-reactive-executor-tomcat dependency from your project. Camel will automatically use the built-in DefaultReactiveExecutor .

Auto-detection from classpath

To use this implementation all you need to do is to add the camel-reactive-executor-tomcat dependency to the classpath, and Camel should auto-detect this on startup and log as follows:

Using ReactiveExecutor: camel-reactive-executor-tomcat
