>          Issue Type: Bug
>          Components: Marshalling
>    Affects Versions: 9.4.4.Final

> Infinispan is used in embedded mode with MySQL 5.7.28 and JDBC Store
> NPE occurs when we try to call Cache.isEmpty() while using MySQL 5.7.28 (server installed on Windows platform). The call goes to AbstractDelegatingCache and the NPE actually occurs in the JdbcStringBasedStore. The issue does not occur if the same server version is installed on Linux 
> The stack trace is as below.
> {noformat}
> java.lang.NullPointerException
