# Java HttpClient CLOSE_WAIT Troubleshoot

Sample project to track [JDK-8221395](https://bugs.openjdk.java.net/browse/JDK-8221395) and [JDK-8236596](https://bugs.openjdk.java.net/browse/JDK-8236596) bug fixes.

Download the desired distributions from the [archive](https://www.oracle.com/java/technologies/javase/jdk11-archive-downloads.html) to test the scenarios. Reference:

- `jdk-11.0.5` - Bug reported

- `jdk-11.0.6` - Fix backported from JDK 13

- `jdk-11.0.15+10` - Most recent version (as of today)

Get the dependencies and compile the project:

```sh

mvn install

mvn compile

```

Set the `JAVA_HOME` environment according to the desired test. Must be set on both client and server bash sessions.

```sh

# Issue should happen

export JAVA_HOME='/opt/java/jdk-11.0.5'

# Issue should NOT happen

export JAVA_HOME='/opt/java/jdk-11.0.15+10'

```

Execute the code to generate the connections:

```sh

# Start the mock server

mvn exec:java -pl server

# Trigger client connections using HttpClient

mvn exec:java -pl client

```

Display connections to check if they are in a lock state:

```sh

ss -np | grep ''

```
