ERROR [main] AmbariServer:1017 - Failed to run the Ambari Server java.lang.NoClassDefFoundError: Could not initialize class javax.crypto.JceSecurity

Hello Experts.

We have HDP 2.5.0 cluster and recently migrated JDK from Oracle to OpenJDK.  Now after rebooting servers, Ambari does not start.

The error in log file is:

"02 Dec 2021 20:16:04,161 INFO [main] CertificateManager:76 - Certificate exists:true
02 Dec 2021 20:16:04,161 INFO [main] KerberosChecker:128 - Skipping Ambari Server Kerberos credentials check.
02 Dec 2021 20:16:04,164 ERROR [main] AmbariServer:1017 - Failed to run the Ambari Server
java.lang.NoClassDefFoundError: Could not initialize class javax.crypto.JceSecurity
at javax.crypto.SecretKeyFactory.nextSpi(SecretKeyFactory.java:295)
at javax.crypto.SecretKeyFactory.<init>(SecretKeyFactory.java:121)
at javax.crypto.SecretKeyFactory.getInstance(SecretKeyFactory.java:160)"

We guess we missed to run "ambari-server setup" to reconfigure the new JDK.

As we didn't it before and want to know if there is any risk of loosing data after the setup.

Some tip or advise?

Regards
