Longer running Linux instance crash, SIGBUS GtkApplication.staticScreen_getScreens()

[kasemir]

After running for a longer time (>day), instances executed via ssh -YC on another Linux computer have crashes several times like this:

# A fatal error has been detected by the Java Runtime Environment:
...
#  SIGBUS (0x7) at pc=0x00007efbf704a9b2, pid=18271, tid=18299

Not a show-stopping problem. May be caused by local IT interacting with the desktop configuration to enforce local standards.

Just happened when the client computer screen is un-locked, which might indeed trigger an update of the display settings. This was with Red Hat Enterprise Linux Workstation release 7.5 and Java 10+46.
