Jasperreports 7.5 SRC Keystore troubles

Hi,

I'm building a clean 7.5 instance in a Tomcat 9.0 server; I'm always getting the same starting error trace:

2020-02-21T08:48:11,330 ERROR ContextLoader,main:350 - Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'themeSource' defined in ServletContext resource [/WEB-INF/applicationContext-themes.xml]: Cannot resolve reference to bean 'themeCache' while setting bean property 'themeCache'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'themeCache' defined in ServletContext resource [/WEB-INF/applicationContext-themes.xml]: Cannot resolve reference to bean 'unsecureRepositoryService' while setting bean property 'repositoryService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hibernateRepositoryService' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Cannot resolve reference to bean 'hibernateRepositoryListeners' while setting bean property 'repositoryListeners'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hibernateRepositoryListeners' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Cannot resolve reference to bean 'schedulingReportDeleteListener' while setting constructor argument with key [0]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'schedulingReportDeleteListener' defined in ServletContext resource [/WEB-INF/applicationContext-report-scheduling.xml]: Cannot resolve reference to bean 'reportSchedulingService' while setting bean property 'schedulingService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'reportSchedulingService' defined in ServletContext resource [/WEB-INF/applicationContext-report-scheduling.xml]: Cannot resolve reference to bean 'securedReportJobsPersistenceService' while setting bean property 'persistenceService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'securedReportJobsPersistenceService': FactoryBean threw exception on object creation; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'reportJobSecurity' defined in ServletContext resource [/WEB-INF/applicationContext-report-scheduling.xml]: Cannot resolve reference to bean 'authenticationManager' while setting bean property 'authenticationManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'authenticationManager' defined in ServletContext resource [/WEB-INF/applicationContext-security.xml]: Cannot resolve reference to bean 'daoAuthenticationProvider' while setting constructor argument with key [0]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'daoAuthenticationProvider' defined in ServletContext resource [/WEB-INF/applicationContext-security.xml]: Cannot resolve reference to bean 'passwordEncoder' while setting bean property 'passwordEncoder'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'passwordEncoder': Unsatisfied dependency expressed through field 'keystoreManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'keystoreManager': Invocation of init method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.jaspersoft.jasperserver.crypto.KeystoreManager]: Please make sure that `create-keystore` was executed; nested exception is java.lang.RuntimeException: KeystoreManager was never initialized or there are errors while instantiating the instance.

I have a Java 1.8 VM for the Tomcat Server, and I have also deployed a 7.2 server in the same way as I'm doing this one, working completely fine.

What I'm missing here? Thank you
