Can't start OpenJump

[Alexander Rumanovsk]

Hi all,

I've installed OpenJump on my Fedora 23 without problems, but when I try to start it, I get the following error:

---Start OJ---

Any clue what is happening?

Hi,

Error comes from some check of the headless mode

Perhaps your java starts for some reason in a headless mode (believes
there is no display).

hi Alex,

Jukka is right. most likely you just miss the full java runtime. check this page, it has some hints
