Archie Cobbs updated HTTPCLIENT-1738:
-------------------------------------
Fix Version/s: (was: 4.5.2)
> CLONE - "deflate" encoding issue : java.util.zip.ZipException: invalid block type
> ---------------------------------------------------------------------------------
>
> Key: HTTPCLIENT-1738
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1738
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Environment: Windows
> Reporter: Archie Cobbs
> Priority: Minor
>
> 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
