JSON-B adapters + JAX-RS 2.1 + hot-deploying = not working

## Short version

### Cannot use hot-deploy with adapters

When using `JsonbTypeAdapter`, hot deploying makes the adapters unusable. Configuration is:

- Payara 5.0.0.Alpha3 Full
- Java EE 8: same behaviour whether using `javaee-web-api` (standalone war module) or `javaee-api` (ear application made of 1 x Ejb + N x web)
- aiming for JAX-RS 2.1
- using JSON-P 1.1 and JSON-B 1.0
- Yasson dependency is not explicitly used, it seems that the implementation of Payara takes precedence
- JPA not used
- `JsonbTypeAdapter` have injected `@EJB`
- Netbeans 8.2

When loading the fake database, a `@Singleton`, I successfully test if the `JsonbTypeAdapter` are working

### Workaround

> Simply reboot the application server. There is no need to manually re-deploy first, the last hot-deploy will be taken into account.

---

## Context:

I'm comparing `JSON-B 1.0` vs `JSON-P 1.1`. I faked entities so that JPA is not involved yet. Full source code is [here](https://github.com/Xsylum/java-ee/tree/master/jax-rs).

_{There is no testing page. REST testing is done with [Google's Postman](https://www.getpostman.com/)}

My simple entities look like:

**Company** ([full code link](https://github.com/Xsylum/java-ee/blob/master/jax-rs/src/main/java/com/playground/jax/rs/organisation/Company.java))
```java
@JsonbPropertyOrder(PropertyOrderStrategy.ANY)
public class Company{
private Long id;
private String name;

@JsonbTypeAdapter(DepartmentListAdapter.class)
private List departments; // fake a @OneToMany relationship
//...
}
```

**Department** ([full code link](https://github.com/Xsylum/java-ee/blob/master/jax-rs/src/main/java/com/playground/jax/rs/organisation/Department.java))
```java
@JsonbPropertyOrder(PropertyOrderStrategy.ANY)
public class Department{
private Long id;
private String name;

@JsonbTypeAdapter(CompanyAdapter.class)
private Company company; // fake a @ManyToOne relationship
// ...
}
```

## JSON-B & Adapter

To avoid circular serialization (Company -> Department -> Company) I have the following adapters:

1. [`DepartmentListAdapter implements JsonbAdapter, JsonArray>`](https://github.com/Xsylum/java-ee/blob/master/jax-rs/src/main/java/com/playground/jax/rs/organisation/DepartmentListAdapter.java)
2. [`CompanyAdapter implements JsonbAdapter`](https://github.com/Xsylum/java-ee/blob/master/jax-rs/src/main/java/com/playground/jax/rs/organisation/CompanyAdapter.java)

Adapter works fine with a basic:

```java
Jsonb jsonB = JsonbBuilder.create();
jsonB.toJson(departmentsList);
```

## Errors

As said earlier, in both situation, a server reboot fixes the issue.

### Without using EJB

If I comment out the `@EJB` injection (`adaptFromJson(...)` always return `null`), a `ClassCastException` is triggered after the first hot-deploy:

- when requesting companies list:
> `java.lang.ClassCastException: com.playground.jax.rs.organisation.Department cannot be cast to com.playground.jax.rs.organisation.Department`

- similarly, when requesting departments list:
> `java.lang.ClassCastException: com.playground.jax.rs.organisation.Company cannot be cast to com.playground.jax.rs.organisation.Company`

Stacktrace is:

### With EJB

Similarly, if I leave the `@EJB` injection, the error becomes
