Hi!

In this function, seems one could not known what database needs the
plugin. That's bad.

In current engine implementation, multiple attachments has multiple
metadata caches and plugins instances.

But Java External Engine plugin loads classes stored in the database,
and they should be loaded in a classloader per database, not per
attachment, which would be heavy.

The most direct way to do that would be to return a single
IExternalEngine for these attachments sharing the same database (in the
same process).

How to do that?
