Jaspersoft Studio version: 6.9.0.
Jaspersoft Server version: 7.2
In Jaspersoft Studio, I had created a server connection. But, when I try to connect, an error was occurred.
Attached here with the screenshot.
The steps to reproduce are just simple. In Jaspersoft Studio 6.9.0, create a connection to the Jaspersoft Server and then connect to it, you will see the error.
In later comments, I will attach the exception message I saw in error dialog, and Jaspersoft Studio log file.
