Solutions

1. Confirm the id via the list endpoint GET /fruits before fetching by id.
2. Ensure the tenant identifier matches the tenant owning the row.
3. Handle 404 in the client as 'not found' and do not retry.
4. Create the entity if it should exist.

Example fix

// before
GET /fruits/999   // 404
// after
GET /fruits/1     // use an id that exists for the current tenant

List<Integer> ids = target("/fruits").request().get(new GenericType<List<Fruit>>(){})
        .stream().map(Fruit::getId).collect(Collectors.toList());
if (!ids.contains(id)) { throw new IllegalStateException("Fruit " + id + " not found"); }

try {
    return target("/fruits/" + id).request().get(Fruit.class);
} catch (WebApplicationException e) {
    if (e.getResponse().getStatus() == 404) { return Optional.empty(); }
    throw e;
}

When it happens

Trigger: GET /fruits/{id} with an id that has no row, or a row that belongs to a different tenant than the one selected by the request's tenant identifier.

Common situations: Wrong tenant header/datasource so the row is in another schema, entity deleted concurrently, stale bookmarked URL, or off-by-one/auto-increment gap ids.
