The Join seems to work, but a FeatureLayer based on a FeatureSource that has a
Joined Query has no output.
FeatureCollection featureCollection =
featureSource.getFeatures(query);
FeatureLayer layer = new FeatureLayer(featureCollection,
styleGeometry);
When I do featureCollection.size() it gives me the correct size of the joined
query.
The map with the FeatureLayer on it, displays nothing with StreamingRenderer.

Will this work when may threads are calling the lookup function and use the

No, it won't, since a connection is something that cannot be used by different
threads.
A slightly different approach would be to store the connection in a thread
local, and then
find some way to close it once you're done.
Or, you'll have to lookup the connection from the data source, and close it,
every time.
It's not that expensive, the datasource is a connection pool no?
The expensive part will be to have to run so many queries, one per feature
Joining does work, there are tests to prove it, have a look at JDBCJoinTest and
its subclasses
for examples of usage.
