---------------------------------------
Summary: FileNotFoundException on Cached Variant
Key: HTTPCLIENT-1299
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1299
Project: HttpComponents HttpClient
Issue Type: Bug
Components: Cache
Affects Versions: 4.2.3
Environment: OpenJDK 64-Bit Server VM (6b24-1.11.5-0ubuntu1~12.04.1)
Reporter: James Leigh
This bug was introduced in org.apache.http.impl.client.cache.BasicHttpCache in
4.2.3.
cacheAndReturnResponse takes the response and passes it to storeInCache. It
then calls generateResponse with the *same* response resource. The problem is
that storeInCache passes the resource to doGetUpdatedParentEntry, which makes a
copy and *deletes* the resource it was passed (oldResource).
This did not occur in 4.2.2 because in 4.2.2 doGetUpdatedParentEntry did not
delete the resource. If the resource is being deleted after it is copied in
4.2.3, then it must not be used to generateResponse.
Here is a stack trace with line numbers.
