Subject: VisualDCT not starting on RHEL7

Dear tech-talkers,

On RHEL7 (7.3 and 7.4), VisualDCT immediately quits when configured to load DBDs at start.

What we see:
Moving our system from RHEL 6 to RHEL 7, the VisualDCT tool doesn’t correctly start up anymore. We set the dbd files to read at startup via an env variable, and VDCT seems to start up normally, but then bails out complaining that it did not load any DBDs:
$ vdct
Loading VisualDCT v2.6.1280...


Directive to load DBD: '/opt/codac-6.0/epics/dbd/base.dbd'.
Directive to load DBD: '/opt/codac-6.0/epics/dbd/pxi6259.dbd'.
Directive to load DBD: '/opt/codac-6.0/epics/dbd/nisync.dbd'.
Directive to load DBD: '/opt/codac-6.0/epics/dbd/nisync-generalTime.dbd'.
No DBD loaded! Exiting...

The DBD files are fine, the same jar that works on RHEL 6 shows this behaviour on RHEL 7. Java versions are different, but not that different (1.8.0_101 vs. 1.8.0_141).

Does that ring any bell?

Thanks a lot for your help,
~Ralph
