Unrecognized VM option 'TieredStopAtLevel=1'


I want to install syslog-output plugin, i followed the doc (https://www.elastic.co/guide/en/logstash/current/plugins-outputs-syslog.html#plugins-outputs-syslog-severity) and ran the command
bin/plugin install logstash-output-syslog

error :
Unrecognized VM option 'TieredStopAtLevel=1'
Could not create the Java virtual machine.

Which JVM (run java -version)? Logstash requires Java 7 or later.

OpenJDK Runtime Environment (IcedTea 2.6.4) (7u95-2.6.4-1~deb7u1)
