+/**
+ * An {@link SSLSocketFactory} decorator that stamps a fixed host onto every
socket it creates.
+ * <p>
+ * BouncyCastle's JSSE takes the hostname for HTTPS endpoint identification
from the socket itself
+ * rather than from the URL. {@link java.net.HttpURLConnection}, which Nimbus
uses to fetch a JWKS,
+ * creates the socket without a host and connects it by address, so under the
BouncyCastle FIPS
+ * provider the hostname arrives as {@code null} and endpoint identification
fails with
+ * "No hostname specified for HTTPS endpoint ID check" before the certificate
is ever examined.
+ * That happens even when the certificate carries a matching iPAddress SAN.
+ * <p>
+ * Setting the host restores the check: BouncyCastle matches an IP literal
against the
+ * certificate's iPAddress SANs and a name against its dNSName SANs.
Verification is preserved,
+ * not bypassed.
+ * <p>
+ * The host is applied through {@code setHost(String)}, declared by
+ * {@code org.bouncycastle.jsse.BCSSLSocket}. That type is reached
reflectively so Knox does not
+ * take a compile dependency on the BouncyCastle TLS provider, which is
present only in FIPS
+ * deployments. On sockets that do not expose the method this decorator is a
no-op, which is
+ * correct for the stock JSSE: it identifies IP endpoints from the URL already.

Review Comment:
Agreed! I'll update it.

> BC-FIPS HostnameUtil.checkHostname refuses IP literals for the HTTPS
