Oleg Kalnichevski commented on HTTPCLIENT-1103:
-----------------------------------------------
We are probably looking at the second half of July as a likely release
time-frame for 4.1.2 and Q1 2012 for 4.2

> Key: HTTPCLIENT-1103
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1103
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient
> Affects Versions: 4.1.1
> Environment: jdk6
> Reporter: Reuben Pasquini
> Fix For: 4.1.2, 4.2 Alpha1

> Invoking EntityUtils.consume( entity ) after a previous call to
> entity.getContent (and subsequent processing of the content) throws a
> java.io.EOFException when gzip decompression support is enabled via
> ContentEncodingHttpClient or some similar mechanism. I invoke
> EntityUtils.consume in a 'finally' block - maybe I'm not using the API
> correctly ... ?

> I believe the problem is that the underlying DecompressingEntity allocates a
> new GzipInputStream for each call to getContent, rather than caching the
> stream created by the first getContent call.

> The "CustomProtocolInterceptors" example has the same bug:
> http://hc.apache.org/httpcomponents-client-ga/examples.html
> I worked around the problem implementing the example with my own
> GzipDecompressingEntity (scala code - lazy value not evaluated till accessed):
> class GzipDecompressingEntity( entity:http.HttpEntity) extends
> http.entity.HttpEntityWrapper(entity) {
> private lazy val gzipStream = new GZIPInputStream( entity.getContent() )
>
> /**
> * Wrap entity stream in GZIPInputStream
> */
> override def getContent():java.io.InputStream = gzipStream
> /**
> * Return -1 - don't know unzipped content size
> */
> override def getContentLength():Long = -1L
> }
