Hi all,

when trying to consume deflate content coded responses I get "java.util.zip=
.ZipException: invalid stored block lengths" exception.

server mock looks like:

header is byte array=20

Deflater def =3D new Deflater(Deflater.BEST_COMPRESSION);
def.setInput(content);
def.finish();
contentLength =3D def.deflate(compressedContent);

// concat header and content
System.arraycopy(header, 0, response, 0, header.length);
System.arraycopy(compressedContent, 0, response, header.length, contentLeng=
th);

// sending response to socket
OutputStream outputStream =3D null;
BufferedOutputStream bos =3D null;
outputStream =3D socket.getOutputStream();
bos =3D new BufferedOutputStream(outputStream);
bos.write(Utils.buildHttpResponseWithCompressedBody(messagedata.response));
bos.flush();
bos.close();
outputStream.close();
...
socket.close();

client side looks like:

...
response =3D client.execute(method);
entity =3D response.getEntity();
...
DeflateDecompressingEntity dde =3D new DeflateDecompressingEntity(entity);
...
         bais =3D (ByteArrayInputStream) entity.getContent();

What could cause this exception?

If I use gzipped content (with appropriate classes) I get a "No GZIP format=
" exception. When I decompress content directly after compression I get the=
 right content. I guess there must be a general problem with my setup.

Kind regards,
