1. "supporting setting JVM options via the `jvm.options` file or the environment variable `ES_JAVA_OPTS`"

- Does elasticsearch merge settings from both sources?

1. We set java options in jvm.options and JAVA\_OPTS. When I run jinfo -flgas and jconsole, only the settings set in JAVA\_OPTS are displayed as VM parameter. Elasticsearch runs in Windows server.  
Do I have to choose one of them?

2. Are all the settings in JAVA\_OPTS ignored unless they are set in ES\_JAVA\_OPTS even if I start Elasticsearch by running a new process of "java\_home/bin/java JAVA\_OPS ES\_PARAMS org.elasticsearch.bootstrap.Elasticsearch -cp ES\_CLASS\_PATH" ?

By looking at bin/elasticsearch source file, I realize jvm options from jvm.options and ES\_JAVA\_OPTS are merged. Thanks!
