core-io 1.7.11(및 그에 따른 Java SDK 2.7.11)까지는 TLS/SSL 연결에서 호스트 이름 확인이 활성화되지 않으며 특정 환경에서 보안 위험이 될 수 있습니다.
Java 6 (JDK 1.6 – the older SDK baseline version) did not support hostname verification out of the box. Once the SDK moved to Java 7 (Java 1.7) as the baseline, adding support was possible. This happened in jvm-core 1.7.11 (which translates to java-client 2.7.11). It is not possible in earlier versions to manually add it as a workaround, because the facilities to customize it accordingly are not exposed. Note that in order to not break applications that rely on the old behavior, hostname verification is still disabled by default, but can be enabled in the SDK configuration (CouchbaseEnvironment class).
