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 SniHandler(AsyncMapping<? super String, ? extends SslContext> mapping,
                      int maxClientHelloLength, long handshakeTimeoutMillis) {
        super(maxClientHelloLength, handshakeTimeoutMillis);
        this.mapping = (AsyncMapping<String, SslContext>) ObjectUtil.checkNotNull(mapping, "mapping");
    }
