Answer 1

It seems like you need the latest version of the jdk.

Check it out here from the requirement matrix. Scroll down to Elasticsearch 5.1.x within the Product and JVM section where it says that you got to have Oracle JVM 1.8u40+.

EDIT:

What if you run your jvm as such, by increasing your heapsize:

-XX:MaxHeapSize=512m

or what if you set it from the the Environment Variables:

Go to Start > Control Panel > System > Advanced system settings > advanced(tab) > Environment Variables → System Variables → New and then the following values:

Variable name: _JAVA_OPTIONS
Variable value: -Xmx512M

This SO could be helpful!

Answer 2

Follow below steps

1. Use latest version of java8

2. Goto config folder and open elasticsearch.yml file then do below changes.

Uncomment the cluster.name and node.name in elasticsearch.yml like below and give your own cluster and node name.

cluster.name: ESCluster

node.name: ESNode

3.Change heap size in jvm.options

-Xms1g

-Xmx1g

4. Goto bin folder then run elasticsearch.bat

Answer 3

Could you alter your 'ELASTICSEARCH DIR'/config/jvm.options?

Try altering this:

-Xms2g
-Xmx2g

into

-Xms1g
-Xmx1g

or even lower (like 512m)
