Named SMB connection so Hop can read and write a Windows or Samba share without mounting it. The scheme is the connection name (finance:///reports/daily.csv). Host, share, and password stay on the metadata.

The client is smbj and speaks SMB 2.0.2 through 3.1.1. SMB1 is not offered. Sign-in in this version is NTLMv2 (username, password, optional domain) and guest. Kerberos is the next authenticator and plugs into the same smb-connection metadata type.

Integration tests run as integration-tests/smb in the Jenkins suite. Samba is a compose service with SMB1 off, NTLMv2 only, and mandatory signing, plus a second service that requires SMB3 encryption. The file operations are shared pipelines under integration-tests/vfs. Pointing the other VFS drivers at those pipelines is #8719.

fixes #8671

A few issues:

Missing bouncycastle lib during assembly.
Update dependency to org.bouncycastle:bcprov-jdk18on:1.86 (security)

Plus working with the VFS explorer:

I suspect there's a timer going off to clean up and it goes wrong.
