I have SQL Dev 18.1 installed on several Windows boxes, but on one of them I am not able to open a new SQL Worksheet for any connection. It worked previously on this same box and SQL Dev version.
In the Logging Pane, whenever I attempt to open a new SQL Worksheet I see a new log entry:
Level=Severe
Source=oracle.dbtools.worksheet.editor.OpenWorksheetWizard
Message=null at oracle.dbtools.worksheet.editor.OpenWorksheetWizard.openNewTempWorksheet(OpenWorksheetWizard.java:526)
This happens regardless of how I try and open the worksheet ( Right-Click from Navigator; SQL Worksheet drop down selector ; Open report in SQL Worksheet).
I haven't noticed other issues. I am able to open new connections and run reports and bring up object editor tabs, etc...
Windows Server 2008 is the O/S. This particular server is a shared VM "Jump Box" that several people RDP into so rebooting isn't an option for now.
Any suggestions on how to troubleshoot this issue? I haven't tried to re-install SQL Dev and would like to use this as an opportunity to learn a little about general troubleshooting approaches for SQL Dev
P.S. Yes, I did search but didn't find this issue already posted.
