KDE5: minimwatch can not create sys tray icon

[ReneZ]

With regards to the earlier referenced post; I'm in the same situation again (still using Ubuntu 12.04 LTS). I had it running OK for some time. but it changed again with the upgrade to Minimwatch 8.0.3 (? - latest - the one you had to install separately). Meantime it also doesn't work any more on my W10/64 machine, after the same upgrade. It now throws a Java exception, however its incomplete (can't see what the message is as it disappears too quick - something about "unsatisfiedlinkerror"). Haven't had time to look further. There was a recent upgrade to Java, don't know if that's the issue.
