------------------------------------

             Summary: NPE while using MySQL 5.7.28
                 Key: ISPN-11088
                 URL: https://issues.redhat.com/browse/ISPN-11088
             Project: Infinispan
          Issue Type: Bug
          Components: Marshalling
    Affects Versions: 9.4.4.Final
            Reporter: AshokKumar NV


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.
