we never trust java being secure so we don't have any management console based on java. NBU used to be installed without java but now the installation option doens't provide that.
is the future of NBU java? or in version 8.x we can have a browser based management console instead?
7.7.1 or 7.7.2 was the last supported version with non-Java console . Since then, only Java console is available. Yes there is a web browser console developed (some new things especially in 8.1.2 version), however its functionality is still very limited in comparison with Java console.
No, the previous .EXE console is not coming back. I'm still not sure if the web console will eventually replace the Java one (it's really limited right now), I had hopes the "web console" windows service was a hint towards this but it only manages certificates.
On the bright side, the Java Console now does a lot of things it previously couldn't (like copy-pasting ).
