Curve25519 - java.lang.NoSuchMethodError

Hi,

When running a program in a linux machine with Curve25519 being negotiated, I'm getting the following error:

2019-07-06 08:05:26 [reader] DEBUG n.s.sshj.transport.KeyExchanger - Received SSH_MSG_KEXINIT
2019-07-06 08:05:26 [reader] DEBUG n.s.sshj.transport.KeyExchanger - Negotiated algorithms: [ kex=curve25519-sha256; sig=ssh-ed25519; c2sCipher=aes128-ctr; s2cCipher=aes128-ctr; c2sMAC=hmac-sha1; s2cMAC=hmac-sha1; c2sComp=none; s2cComp=none ]

The same runs successfully in windows machine but, here, is not using curve25519-sha256:
2019-07-06 11:03:37 [reader] DEBUG n.s.sshj.transport.KeyExchanger - Negotiated algorithms: [ kex=diffie-hellman-group1-sha1; sig=ssh-ed25519; c2sCipher=aes128-ctr; s2cCipher=aes128-ctr; c2sMAC=hmac-sha1; s2cMAC=hmac-sha1; c2sComp=none; s2cComp=none ]

I'm using in my project:

com.hierynomus
sshj
0.27.0

I'm importing in my maven project bouncycastle:

org.bouncycastle
bcprov-jdk15on
1.62


org.bouncycastle
bcpkix-jdk15on
1.62


org.bouncycastle
bcmail-jdk15on
1.62

And, registring the Provider in my code before set the DefaultConfig this way:
SecurityUtils.setRegisterBouncyCastle(true);

Can this be a bug, or, I'm missing something?

Thanks,
