Hi Oleg,
Thank you for getting back to me very promptly. We will go with the newer
version 4.3.1.

> DefaultNHttpClientConnection enters infinite loop when consuming chunked

>
> Key: HTTPCORE-367
> URL: https://issues.apache.org/jira/browse/HTTPCORE-367
> Project: HttpComponents HttpCore
> Issue Type: Bug
> Components: HttpCore NIO
> Affects Versions: 4.3
> Environment: Java 1.7.0_40
> Reporter: Paul McLellan
> Fix For: 4.3.1
>
>
> We recently upgraded from 4.3-beta2 to 4.3 and noticed that our client was
> not fully consuming large (~64K) responses from the server. A little digging
> led us to the 'consumeInput(NHttpClientEventHandler)' method of
> DefaultNHttpClientConnection. Within this method, the following logic from
> 4.3-beta2:
> if (this.contentDecoder != null && (this.session.getEventMask() &
> SelectionKey.OP_READ) > 0) {
> handler.inputReady(this, this.contentDecoder);
> if (this.contentDecoder.isCompleted()) {
> // Response entity received
> // Ready to receive a new response
> resetInput();
> }
> }
> Has been replaced with:
> if (this.contentDecoder != null) {
> // Loop until there is interest in input,
> // decoder is not done and there is buffered session data
> while ((this.session.getEventMask() & SelectionKey.OP_READ) > 0) {
> handler.inputReady(this, this.contentDecoder);
> if (this.contentDecoder.isCompleted()) {
> // Response entity received
> // Ready to receive a new response
> resetInput();
> break;
> }
> if (!this.inbuf.hasData()) {
> break;
> }
> }
> }
> This is causing the dispatcher thread to become stuck in an infinite loop
> when it reaches the end of the first chunk because the input buffer contains
> a single character ('\r') that is never consumed by the ChunkDecoder. Prior
> to the upgrade this method would exit and the dispatcher thread would be able
> to read the next chunk from the inbound channel.
> Can you help with this issue please? Any assistance/guidance would be greatly
> appreciated.
> Thanks.
