net view uses RPC which we don't do. We use the older RAP protocol for
listing shares. Doing smbclient -L would be more comparable. But a timeout
sounds like there's a protocol error somewhere. I suspect it is because
you're using security = share. I don't recall seeing anyone use that in
several years. To get a difinitive answer you would have to get a packet
capture of smbclient -L working and the jcifs ListFiles.java example
failing. Otherwise, I'll add this to TheList for future investigation
(security = share is not a high priority - Samba4 doesn't even support
it IIRC).

Actually from accountName above it doesn't look like you're successfully
setting credentials either. See the Overview page of the API documentation
for instructions on how to set jcifs properties.
