java.nio.channels.ClosedChannelException while using httpclient

[HiteshS]

Hello all,

We are using JRJC httpclient (com.atlassian.httpclient.api.HttpClient interface) to get data from jira.

httpclient = (new AsynchronousHttpClientFactory()).createClient(new URI(baseURL), authenticationHandler);

AsynchronousHttpClientFactory defined in package com.atlassian.jira.rest.client.internal.async.

However, we are getting the following exceptions in logs:

org.apache.http.impl.nio.client.LoggingAsyncRequestExecutor:org.apache.http.impl.nio.client.LoggingAsyncRequestExecutor.exception(LoggingAsyncRequestExecutor.java:74) ERROR - http-outgoing-65 [CLOSED] HTTP protocol exception: nulljava.nio.channels.ClosedChannelException

No API is failing but how to resolve the errors?

I went through various related questions on this forum, but didn't get what I can apply in my case.

Hi Hitesh!

Is your JIRA SSL self signed? Have a look here: How to resolve JRJC ?

[HiteshS]

Our jira instance is on atlassian cloud.

Anyway this looks like some problem with SSL. Maybe java keystore does not have appropriate entry for certificate issuer (for my JIRA it's DigiCert). I suggest you to try very simple sample with apache http client accessing some REST method of your JIRA.
