                                (was: 8.4)
    Workaround Description: On 8.4+ should a similar problem (post load exception) arise with cached metadata, the model or vdb property cache-metadata can be set to false to disable the metadata caching.

> Occurs on server startup. Deployed a vdb and was able to connect, etc.  Bounced the server and now get a bunch of these errors:

> Looking at MetadataFactory I noticed the following:
>                      Datatype dt = this.builtinDataTypes.get(c.getDatatype().getName());
>                         if (dt != null) {
>                                 c.setDatatype(dt);
>                         } else {
>                                 //must be an enterprise type
>                                 //if it's used in a single schema, we're ok, but when used in multiple there's an issue
> -->                                addDatatype(dt);
>                         }
>                 }
> ---------
> that addDatatype(dt) was passing dt when null, and therefore, in addDatatype, the NPE was caused when datatype.getName() is called.  But I think what was intended was to pass in c.getDatatype() when it wasn't found in the builtinDataTypes.
