If we try to runtime change the tracing.categories at runtime and we put an empty list on it, we get a parsing error.

Here is an example of the execution.

private void updateConfig() {
      cacheManager.administration().withFlags(CacheContainerAdmin.AdminFlag.VOLATILE)
            .updateConfigurationAttribute(cache.getName(), "tracing.categories","");
   }

This is usually not required since we can update "tracing.enable" to "true" to disable the tracing on a given cache at runtime.
