> The {{HttpEntity}} interface provides a method for indicating whether or not an entity
can be automatically retried. While investigating an issue with corruption of encrypted uploads
in the [java-manta library|https://github.com/joyent/java-manta] I discovered that requests
were being automatically retried in the event of a 503 response from the server. Stepping
through the execution path led me to discover that {{ServiceUnavailableRetryExec}} does not
check the supplied {{HttpRequest}} to determine whether or not it can be safely retried. We've
implemented a fix within java-manta in our subcclass of {{DefaultServiceUnavailableRetryStrategy}}
but this seems like it could bite others as well so I thought it would merit a bug report.
> The included patch corrects this behavior. Checked that {{mvn verify}} completes successfully.
Please let me know if there are any questions or other modifications that I need to make in
order to contribute this patch.
