Frequent java.io.IOException: broken pipe messages appearing in logs

Issue Summary

After upgrading from JIRA 6.x to JIRA 7.1.x, the following trace can be found in the logs mentioning "Broken Pipe".

Steps to Reproduce

1. A connection is established by between the Jira application server and a client (anyone connecting to Jira).
2. The connection is closed unexpectedly (cancelling download, killing browser, closing tab while page is loading, etc).

Expected Results

No problem is perceived and no exception is thrown in logs.

Actual Results

The UI does not perceive any problem but the below exception is thrown in the atlasian-jira.log file:

 http-nio-8080-exec-5 ERROR      [o.a.c.c.C.[.[localhost].[/].[default]] Servlet.service() for servlet [default] in context with path [] threw exception
java.lang.RuntimeException: org.apache.catalina.connector.ClientAbortException: java.io.IOException: Broken pipe

Notes

• Sometimes this is thrown so frequent in the logs that it is spamming the logs
• The most common causes for this exception to appear are covered in our KB article ClientAbortException: java.io.IOException: Broken pipe
• There are variations on the stack trace with the same exception, like this:

  ERROR [o.a.c.c.C.[.[localhost].[/].[default]] Servlet.service() for servlet [default] in context with path [] threw exception
