Recently, after updating to ABAP Core Development Tools (Developer Edition) 3.4.5, I find that SQL Console no longer functions for me with any of my system connections. Specifically the error I get when trying to use SQL Console is "Failed to create the part's controls" with a Java exception (see attachment: eclipse-adt-error.txt). Curiously Data Preview works fine (and I discovered while writing this question that I can click the SQL Console button on a data preview to open it successfully), I'm just not able to open the SQL Console via the contextual menu on the system connection (Eclipse project).
This has persisted as I've tried recreating my Eclipse environment fresh, updating my SAP GUI, and now as I've updated to ABAP Core Development Tools (Developer Edition) 3.6.0.
It would appear this is an error with some aspect of the UI elements for SQL Console being missing so I would think that someone else would have noticed by now but I've not found anything about this here or within support.sap.com.
Details about my system:
Does anyone have expertise on what I can do? Should I submit this as a bug to SAP? If so, how? I can't do so through Eclipse as the bug report tool there doesn't complete. I can't readily find the product/component in support.sap.com to submit an incident. I don't see that ADT is out on github.com/SAP either.
