OpenSpirit Runtime 4.2.0 was released in December of 2015 and certified on RHEL 5 and RHEL 6.5. It can be run on RHEL 7, however, there is an in issue with the Desktop's graphic interface. Specifically if more than one tab was open in the Desktop the tab specific toolbar would disappear.
Environment
RHEL 7x
Resolution
If only one tab is open at at time, then the toolbar shows up.
For example: In the screenshot below, both Copy Manager and Scan Job Manager tabs are open with the Scan Job Mange tab selected. The toolbar for Scan Job Manager is not visible:
If both tabs are closed and then just the Scan Job Manager tab is open, then the toolbar is visible.
