Server cannot start because of in JDK10 class sun.misc.cleaner is missing

[arnosk]

Hello,
I tried to start the server on lubuntu18.04 with default-jdk installed. This is actually openJDK10.0.1
The wallet works normally but when starting the server an error is occuring because the class sun.misc.cleaner is not in openJDK10 anymore. Removing default-jdk and installing openjdk-8-jdk it runs good.

Hi,

Thanks for the alert.

A quick look on the Chronicle component providers issue list shows Java 9 is likely not to work not as well but that they are working on updating their code. When they add support for java 9/10 HEAT will support that java version as well.
