--------------------------------------
    Resolution: Invalid

Hang on a second, there may be something wrong with the compressed data I'm \
receiving.

I'm resolving this issue as invalid for now pending further investigation.

> Key: HTTPCLIENT-1738
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1738
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient
> Affects Versions: 4.5.2
> Environment: Mac OS X
> Reporter: Archie Cobbs
> 
> When trying to GET any nzb files from http://nzbindex.nl with a httpclient request, \
> a ZipException is raised. {code:title=JunitTestFailing.java}
> 	@Test
> 	public void testDeflateIssueFailing() throws ClientProtocolException, IOException \
> {  HttpGet httpget = new \
> HttpGet("http://nzbindex.nl/download/72441827/BackTrack5R3.Gnome.iSO.32bit-LiNUX-0171-bt5r2gis32.par2.nzb");
>   HttpClient client = HttpClientBuilder.create().build();
> 		HttpResponse response = client.execute(httpget);
> 		HttpEntity entity = response.getEntity();
> 		byte[] data = EntityUtils.toByteArray( entity );
> 		Assert.assertEquals( data.length, 423548 );
> 	}
> {code}
> The complete stack trace I get is this:
> {code}
> java.util.zip.ZipException: invalid stored block lengths
> 	at java.util.zip.InflaterInputStream.read(InflaterInputStream.java:164)
> 	at java.io.FilterInputStream.read(FilterInputStream.java:107)
> 	at org.apache.http.client.entity.DeflateInputStream.read(DeflateInputStream.java:144)
>   at org.apache.http.client.entity.LazyDecompressingInputStream.read(LazyDecompressingInputStream.java:68)
>   at org.apache.http.util.EntityUtils.toByteArray(EntityUtils.java:136)
> 	at hclient.HTTPClientTest.testDeflateIssueFailing(HTTPClientTest.java:39)
> {code}
> A workaround I found is to set the Accept-Encoding header to only accept gzip, as \
> follows: {code:title=JunitTestWorking.java}
> 	
> 	@Test
> 	public void testDeflateIssueWorking() throws ClientProtocolException, IOException \
> {  HttpGet httpget = new \
> HttpGet("http://nzbindex.nl/download/72441827/BackTrack5R3.Gnome.iSO.32bit-LiNUX-0171-bt5r2gis32.par2.nzb");
>   httpget.setHeader("Accept-Encoding", "gzip");
> 		HttpClient client = HttpClientBuilder.create().build();
> 		HttpResponse response = client.execute(httpget);
> 		HttpEntity entity = response.getEntity();
> 		byte[] data = EntityUtils.toByteArray( entity );
> 		Assert.assertEquals( data.length, 423548 );
> 	}
> {code}
> Thanks
