I have a single PC with which I connect to two different instances of HANA DB, one is currently on SP21, anotther still on SP16. So I have upgraded (actually, deinstalled and reinstalled) my HANA Studio and Client to SP21.
Now I can connect to HANA DB SP16, but cannot open packages tree -- getting error message "An internal error occurred during: "Fetching Children...". java.lang.NullPointerException" I still can open schemas and browse db, and administet users etc -- just everything in packages is not visible.
Before I create an OSS message, I would like to make sure I am not missing some setting that wasn't there in SP16 Frontend. Or does it look like a genuine bug?
