Copy data to clipboard: Cannot invoke "workbench.db.DbMetadata.getDbSettings()"

[Lis Riba]

Using the Copy Data to Clipboard functionality.

When I press the OK button, SQL Workbench/J returns this error:

Cannot invoke "workbench.db.DbMetadata.getDbSettings()" because "<parameter1>" is null

Strangely enough, this worked fine on Friday, and I haven't made any changes to SQL Workbench, Windows, or Java since then.

Running Build 128 with Java version 17.0.1 (both 64-bit)

Here are the closing lines of workbench.log; I'm neither querying nor returning any blob fields.

Hm.

Exited SQL Workbench and re-launched, and now it's working fine.

In the words of Emily Litella, "Never mind!"

That's really strange. It seems that the connection to the database was closed while the "Copy To Clipboard" was started.
