Above screen shows error after I have tryied to lunch eclipse as root, as simple user it works just fine. In error log file there is some things but I dont understand them.

Does someone had such problem ? And know the anwser

That's a JVM crash, maybe initiated by some eclipse related class. Update to the latest and greatest Java an verify if it is reproduceable.

You have installed Sun/Oracle's JDK but it looks like you are still running OpenJDK. Try calling java -version to make sure, and then call:

update-java-alternatives

to set Oracle's Java as the default.
