URL: https://github.com/apache/mina-sshd/issues/852
### Version
3.0.0-M2
### Bug description
I just trying to execute some commands on a remote machine via SSH using the
ssh_ed25519 signatures..via the following code: The `Types` Enum just contains
simple commands `cat /etc/...` .. nothing more
```java
try (SshClient client = SshClient.setUpDefaultClient()) {
client.setSignatureFactories(List.of(BuiltinSignatures.sk_ssh_ed25519,
BuiltinSignatures.ed25519));
client.setKeyIdentityProvider(KeyIdentityProvider.EMPTY_KEYS_PROVIDER);
client.start();
try (ClientSession session = client.connect(username, host, hostPort)
.verify(Duration.ofSeconds(5))
.getSession()) {
EnumMap<Types, String> result = new EnumMap<>(Types.class);
session.auth().verify(Duration.ofSeconds(5));
Arrays.stream(Types.values()).forEach(type -> {
System.out.println("Command: " + type.command());
try {
OutputStream outputStream = new ByteArrayOutputStream();
session.executeRemoteCommand(type.command(), outputStream,
System.err, StandardCharsets.UTF_8);
result.put(type, outputStream.toString());
} catch (IOException e) {
throw new UncheckedIOException(e);
}
});
return result;
}
}
```
Using 2.16.0 of `sshd-common` and `sshd-core` executed the commands fine but
required the following dependency:
```xml
<dependency>
<groupId>org.bouncycastle</groupId>
<artifactId>bcpkix-jdk18on</artifactId>
<version>1.82</version>
</dependency>
```
which worked fine...
### Actual behavior
but based on the release notes of mina-3.0.0-M2
https://github.com/apache/mina-sshd/blob/sshd-3.0.0-M2/CHANGES.md is mentiones:
https://github.com/apache/mina-sshd/blob/sshd-3.0.0-M2/CHANGES.md#new-features
which I read as no supplemental provider needed and using the one from the
JDK (using JDK25)... ?
but if I execute the above code (NoClassDefFoundError (see logs)..
which looks like it still requires the dependencies... did I misunderstand a
point?
### Expected behavior
Based on my understanding the providers shouldn't be required based on the
usage of JDK25
### Relevant log output
