Label: vulnerable
CWE: CWE-400 \u2014 Uncontrolled Resource Consumption
The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources.

Code:
    public void handleFrame(Frame frame) throws IOException {
        AMQCommand command = _command;
        if (command.handleFrame(frame)) { // a complete command has rolled off the assembly line
            _command = new AMQCommand(); // prepare for the next one
            handleCompleteInboundCommand(command);
        }
    }
