# java-reactor-starter
A starter project to practice [Reactive Programming](https://en.wikipedia.org/wiki/Reactive_programming) with Java and [Project Reactor](https://projectreactor.io).
### Requirements
---
- [JDK 21](https://www.azul.com/downloads/?package=jdk#zulu) from Azul
- [Gradle](https://gradle.org/releases/) 8.4
### Build
---
```bash
./gradlew clean build
```
### Run
---
```bash
./gradlew run
```
### Running with BlockHound
---
[BlockHound](https://github.com/reactor/BlockHound) is a Java agent that detects blocking calls from non-blocking threads.
##### At the entry point
```
public static void main(String[] args) {
BlockHound.install();
// ...
}
```
##### Set the VM options for BlockHound
```
-XX:+AllowRedefinitionToAddDeleteMethods
-XX:+EnableDynamicAgentLoading
```
##### Result when a blocking call is present:
```
reactor.blockhound.BlockingOperationError: Blocking call! java.lang.Thread.sleep
at java.base/java.lang.Thread.sleep(Native Method)
at com.example.Example.lambda$exampleTest$0(Example.java:16)
```
