[undertow-dev] Closing an UndertowOutputStream on broken pipe

I'm streaming data by writing it to an UndertowOutputStream in chunks, and when the the client disconnects before the data is fully sent, I get a Broken pipe IOException when calling .write() (which is expected). I catch that error, then call .close() on the UndertowOutputStream, which throws "java.io.IOException: UT000029: Channel was closed mid chunk, if you have attempted to write chunked data you cannot shutdown the channel until after it has all been written." Is this expected behavior? It seems like it wouldn't be, since none of that pending data can be written. Do I even need to close the OutputStream in this case? Would not doing so leak any resources? Currently, I'm catching and ignoring the IOException thrown by .close(). The full stack traces of the two errors are available at: https://gist.github.com/21d111980352d04816c7 - Toby
