ADDITIONAL SYSTEM INFORMATION :
Simulated in both Linux and Windows. Using JDK12, but it happens with JDK 11 as well.

openjdk version "12" 2019-03-19
OpenJDK Runtime Environment (build 12+33)
OpenJDK 64-Bit Server VM (build 12+33, mixed mode, sharing)

A DESCRIPTION OF THE PROBLEM :
We've been noticing that our HTTP connections are staying in a CLOSE_WAIT state, requiring us to shutdown the Java process in order to release them when using the new API.

In our actual application we run the code in WildFly 16, but I was able to reproduce in standalone code, completely isolated from our source to guarantee there's no interference.

The server host we are calling (IP: 200.186.62.89) seems to be the one that triggers the problem in the client, however the API Impl seems to be unable to terminate the CLOSE_WAIT connections regardless, so I consider it to be an API problem. I don't understand why.

After enabling the debug with "-Djdk.internal.httpclient.debug=true" I found out an "java.io.EOFException: EOF reached while reading". The complete debug log is attached, also with the source code.

If it helps theres this thread I've created in SO: https://stackoverflow.com/q/55271192/3231778

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1) Start the socket server I've pasted in the source code
2) Connect to the socket server with any client (telnet localhost 59090)
3) Server will build an HttpClient instance and send a request to "https://xxxxx.com.br/grb/sb/incidentes/listar" (the IP is xxx.xxx.62.89) and respond with the status code. Client and server will terminate the session.
4) Check operating system for active connections: netstat -an 1 | find "xxxx.xxx.62.89"
5) Every connection established will remain in a CLOSE_WAIT state until the Java process is terminated.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Connections should be released after being in the TCP CLOSE_WAIT state. This state means that the server will end the connection, and the client must do it too. However client is not releasing the connection.
ACTUAL -
Any connection that we start stays on CLOSE_WAIT until the Java process ends.

CUSTOMER SUBMITTED WORKAROUND :
Apache HttpClient and OkHttp libraries are not leaking connections so we are considering to refactor the code and use one of them.
