Searching for the above makes me think sun.misc.Cleaner is a class that's removed when Java's got an update from 1.8 to 1.9. So you might remove general "default-jre" and install "openjdk-8-jre" if you happen to run Ubuntu or derivates. Maybe. Or something like that. Or maybe you should be able to edit start-script to use parameter "-version:1.8*" as man-page suggests but I'm not able to get my system to find any JRE with any version-string. Even -version:1.8.0_171 that same parameter without argument prints gets an error:
$ java -version
openjdk version "1.8.0_171"
OpenJDK Runtime Environment (build 1.8.0_171-8u171-b11-0ubuntu0.17.10.1-b11)
OpenJDK 64-Bit Server VM (build 25.171-b11, mixed mode)
$ java -version:1.8.0_171
Error: Unable to locate JRE meeting specification "1.8.0_171"

Anyway, I guess you have too new java.

The rumour is that AMD has a cpu-mining farm almost read for LTC. They're using their regular cpus that just fail quality control so they can't sell them to consumers/pc-manufacturers.

Thinking this is a sudden damage control move after ..something(?)? not:
This is barely news. You can time travel via link by hitting Ctrl+F "Roadmap", in topmost post of the page to check by yourself.
