Error when launching Gerrit "Starting Gerrit Code Review: FAILED"

[Marcin W]

I've just installed gerrit but I cannot run it due to following error popping up in my log:

My Java version is:

[root@localhost logs]# java --version
java 10.0.1 2018-04-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.1+10, mixed mode)

Java 10 isn't supported yet.

Luca.

This is a known issue with Java 9 (and apparently 10).  See: https://bugs.chromium.org/p/gerrit/issues/detail?id=7843

 

My Java version is:

[root@localhost logs]# java --version
java 10.0.1 2018-04-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.1+10, mixed mode)

Java version above 8 is not supported yet.  There is a workaround (see the issue linked above) but that is not guaranteed.

If possible please downgrade your environment to Java 8.
