Percentage of File Transfer shown abnormally@spark2.6.3

I used spark 2.6.3 to transfer file to another spark 2.6.3 client, but the percentage of file receiver side was shown abnormally and the percentage of transfer side worked well.

After some tests, I found when I used Look&Feel such as Substance Office, it would be shown abnormally.

When I used default Look&Feel, it would work well.

Attached screenshot.



This is not Openfire related but an error in Spark. The issue is currently under investigation.

Oh ~~


I will be careful next time.
