> Infinite loop in LengthDelimitedEncoder due to negative return from
> SSLIOSession.writePlain()

>
> Key: HTTPCORE-417
> URL: https://issues.apache.org/jira/browse/HTTPCORE-417
> Project: HttpComponents HttpCore
> Issue Type: Bug
> Components: HttpCore NIO
> Affects Versions: 4.4.4
> Reporter: Miles Spielberg
> Assignee: Oleg Kalnichevski
> Priority: Critical
> Fix For: 4.4.5, 5.0-alpha2

> SSLIOSession.InternalByteChannel.write(ByteBuffer) does not obey the
> WriteableByteChannel contract. In writePlain(), if the channel is closed, -1
> is returned, but WriteableByteChannel should throw ClosedChannelException in
> this case, and should certainly never return a negative value.
> This leads to an infinite loop in LengthDelimitedEncoder.write().
> AbstractContentEncoder.writeToChannel() returns the -1 from
> SSLIOSession.InternalByteChannel, and this causes remaining to grow without
> bound
> (https://hc.apache.org/httpcomponents-core-4.4.x/httpcore-nio/xref/org/apache/http/impl/nio/codecs/LengthDelimitedEncoder.html#133).
> In my application, I see a stack trace similar to the following:
