    Description

      Hi,

      I've upgraded our current application to Apache ISIS 1.14.0 running on Apache Tomcat 8.5.6 and after that I receive on one environment consistently this error:

      On another environment I receive it sometimes. I haven't found any difference for these environments.

      Both environments have configured JNDI datasource via Tomcat JDBC Pool.

      Thanks & Regards Timothy
