Gian Merlino 846345669d Error handling improvements for frame channels. (#12895) ... * Error handling improvements for frame channels. Two changes: 1) Send errors down in-memory channels (BlockingQueueFrameChannel) on failure. This ensures that in situations where a chain of processors has been set up on a single machine, all processors see the root cause error. In particular, this means the final processor in the chain reports the root cause error, which ensures that someone with a handle to the final processor will get the proper error. 2) Update FrameFileHttpResponseHandler to expect that the final fetch, rather than being simply empty, is also empty with a special header. This ensures that the handler is able to tell the difference between an empty fetch due to being at EOF, and an empty fetch due to a truncated HTTP response (after the 200 OK and headers are sent down, but before any content appears). * Fix tests, imports. * Checkstyle!		2022-08-15 11:31:55 +05:30
