我试图在Linux服务器上安装Gerrit，我下载了war文件并运行命令
java -jar gerrit*.war init --batch --dev -d ~/Gerrit/gerrit_testsite
这是输出
Generating SSH host key ... ed25519...unknown key type ed25519
ecdsa 256...Bits has bad value 256 (too small)
ecdsa 384...Bits has bad value 384 (too small)

done

Reindexing projects: 100% (2/2)
Reindexed 2 documents in projects index in 0.2s (11.0/s)
代替安装指南（https://www.gerritcodereview.com/linux-quickstart.html）中显示的内容：
Generating SSH host key ... rsa(simple)... done

Executing /home/gerrit/gerrit_testsite/bin/gerrit.sh start

有人可以告诉我这里是什么问题吗？
