If an internal exception occurs while packing and the request needs to abort, the HTTP response might already be committed due to progress message having already been delivered to the client. This prevents UploadPackServlet from resetting the response and sending back an HTTP 500 response. Try to catch all exceptions and report internal errors over the sideband stream or as an ERR command during the initial ACK/NAK negotiation phase. This allows JGit to transmit an error message that the user will receive on their console without needing to worry about resetting the (already gone) HTTP response.
