Support of serdes for Throwable/Exception no longer works since Java 17

# Gson version

2.10.1

# Java / Android version

17.0.6 Amazon Corretto

# Used tools

- [ ] Maven; version:
- [ ] Gradle; version:
- [ ] ProGuard (attach the configuration file please); version:
- [ ] ...

# Description

```
public static void main(String[] args) {
System.out.println("11111111111111111111111111111111111111111 " + new Gson().toJson(new ExBean()));
}

static class ExBean {
Throwable throwable = new Exception("xxxxxxxxxxxxxxxxx");
}
```

## Expected behavior

Gson should serialize the ExBean instance with the Throwable field, with stack trace details and related info on the Exception.

## Actual behavior

Gson.toJson errors out with exception. See stack trace below.

# Reproduction steps

1. paste this in a class

```
public static void main(String[] args) {
System.out.println("11111111111111111111111111111111111111111 " + new Gson().toJson(new ExBean()));
}

static class ExBean {
Throwable throwable = new Exception("xxxxxxxxxxxxxxxxx");
}
```

2. Run the main method
