NetWorker (Linux): При модернизации до NetWorker 19.13 не удается настроить сервер AUTHC

Служба проверки подлинности NetWorker сообщает о следующей ошибке при обновлении до версии 19.13.x с предыдущего выпуска:

Exception in thread "main" java.lang.UnsupportedClassVersionError: com/emc/brs/auth/util/ServiceConfigurator has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Та же ошибка возвращается при запуске сценария конфигурации AUTHC: /opt/nsr/authc-server/scripts/authc_configure.sh

[root@lnx-srvr01 linux_x86_64]# /opt/nsr/authc-server/scripts/authc_configure.sh

Specify the directory where the Java Standard Edition Runtime Environment (JRE) software is installed [/opt/nre/java/latest]:

The installation process will install an Apache Tomcat instance.
For optimum security, EMC NetWorker Authentication Service will
use a non-root user (nsrtomcat) to start the Apache Tomcat instance.
If your system has special user security requirements, ensure that proper
operational permissions are granted to this non-root user (nsrtomcat).
Please refer to NetWorker Installation Guide.

Для NetWorker 19.13 требуется Java Development Kit (JDK) 17. Сервер NetWorker использует среду выполнения Java Runtime Environment (JRE) 1.8, которая использовалась в NetWorker 19.12 и более ранних версиях.

[root@lnx-srvr01 linux_x86_64]#  sudo find /usr /opt /lib* -type f -name "java" 2>/dev/null
/opt/nre/java/jre1.8.0_421/bin/java

Установите NetWorker Runtime Environment (NRE) 17.0.1 (или более поздней версии) или лицензированный Oracle JDK 17. NRE можно получить через: https://www.dell.com/support/product-details/en-us/product/networker/drivers

После модернизации до JDK 17 запустите команду authc_configure.sh Сценарий для настройки authc.

[root@lnx-srvr01 ~]# /opt/nsr/authc-server/scripts/authc_configure.sh

Specify the directory where the Java Standard Edition Runtime Environment (JRE) software is installed [/opt/nre/java/latest]:

If your system has special user security requirements, ensure that proper

Please refer to NetWorker Installation Guide.

The Apache Tomcat will use "lnx-srvr01.networker.lan" as the host name.
The Apache Tomcat will use "9090" as the port number.

The NetWorker Authentication Service requires a keystore file to configure encryption and to provide SSL support.

EMC recommends that you specify a keystore password that has a minimum of six characters.

Do you want to use the existing keystore /nsr/authc/conf/authc.keystore [y]?

Specify password for the existing keystore:
The install will use the existing certificate "emcauthctomcat" for Apache Tomcat.
The install will use the existing certificate "emcauthcsaml" for Authentication Service.
