…hutdown Mirror the apache#16391 fix: when decode() is called after the decoder has been closed (via close() or onStreamClosed()), close the input stream instead of ignoring it. This prevents ByteBuf leaks in the non-gRPC Triple HTTP/2 streaming path when late DATA frames arrive after the decoder has started closing. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Fixes #16399
What is the purpose of the change
DefaultStreamingDecoder.decode()does not close the input stream when the decoder has already been closed (closed == true). In the Triple HTTP/2 path, DATA frames are wrapped inByteBufInputStream(content, true)(i.e.,releaseOnClose = true), meaning the underlying pooledByteBufis released only whenInputStream.close()is called. If a late DATA frame arrives asynchronously after the decoder has started closing, theByteBufis never released, causing a leak.This is the exact same bug pattern as #16389, which was fixed by #16391 for
LengthFieldStreamingDecoder. This PR mirrors that fix forDefaultStreamingDecoder.Brief changelog
