    }
Returns the default maximum number of RST frames that are allowed per window before the connection is
closed. This allows to protect against the remote peer flooding us with such frames and using up a lot
of CPU. Note that this flag has no effect if a user specified the value explicitly via
{@link ServerBuilder#http2MaxResetFramesPerWindow(int, int)}.

<p>The default value of this flag is
{@value DefaultFlagsProvider#DEFAULT_SERVER_HTTP2_MAX_RESET_FRAMES_PER_MINUTE}.
Specify the {@code -Dcom.linecorp.armeria.defaultServerHttp2MaxResetFramesPerMinute=<integer>} JVM option
to override the default value. {@code 0} means no protection should be applied.
