--------------------------------------------------
Summary: NullPointerException on 304 Not Modified response
Key: HTTPCLIENT-1274
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1274
Project: HttpComponents HttpClient
Issue Type: Bug
Components: Cache
Affects Versions: Snapshot
Reporter: Francois-Xavier Bonnet
Priority: Minor
Attachments: TestCachingExec.patch.txt
When sending a conditional request (If-None-Match for example) and the backend
responds with a 304 Not Modified, the response contains an HttpEntity but you
get a NullPointerException whenever to try to call one of the methods :
- org.apache.http.HttpEntity.getContent()
- org.apache.http.HttpEntity.writeTo(OutputStream)
I would expect getEntity() to return null if there is no entity in the response.
As a workaround I can test on the contentLength before calling these methods
and call EntityUtils.consume(entity) to get sure that the connection is
released but this makes things more complicated.
