jedis: IllegalStateException: Object has already been returned to this pool or is invalid

[pierredavidbelanger]

Using jooby 1.1.0, with this simple code (inspired by this doc):

use(new Redis());

get("/redis", () -> {
    try (Jedis jedis = require(Jedis.class)) {
        jedis.get("dummy");
        return "HelloWorld!";
    }
});

and this config:

db = "redis://localhost:6379"

When I access /redis the first time it works, then every other request fails with:
