Michael Pujos updated HTTPCORE-263:
-----------------------------------

    Description: 
I've got the exception below reported in my Android app using (repackaged) httpcore 4.1.1:


java.lang.IndexOutOfBoundsException: off: 1088 len: -1 b.length: 8192
	at org.apache.http.util.CharArrayBuffer.append(SourceFile:185)
	at org.apache.http.impl.io.AbstractSessionInputBuffer.readLine(SourceFile:251)
	at org.apache.http.impl.io.HttpRequestParser.parseHead(SourceFile:90)
	at org.apache.http.impl.io.AbstractMessageParser.parseHead(SourceFile:252)
                                                                 parse
	at org.apache.http.impl.AbstractHttpServerConnection.receiveRequestHeader(SourceFile:242)
	at org.apache.http.protocol.HttpService.handleRequest(SourceFile:238)
	at org.teleal.cling.transport.impl.apache.HttpServerConnectionUpnpStream.run(SourceFile:116)
	at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1088)
	at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:581)
	at java.lang.Thread.run(Thread.java:1019)


It seems to be very rare. Stack trace line number (185) in for AbstractSessionInputBuffer doesn't match the exact line number of the offending append() call,
but there are 2 such calls in this function, and it looks like one of them is called with len = -1, triggering the IndexOutOfBoundsException in append()
