schema-registry-start server - ClassNotFoundException

[suresh-Gudapati]

Hi, I am using confluent-schema-registry-7.5.3 (Confluent-Community) with openjdk 11.0.22 and trying to start the SchemaRegistry services but getting “ClassNotFoundException” with the error: Any idea what might be causing this error?
