AEM 6.4 Instance Start up

[#1]

Hello All,

Noticed when starting AEM jar for first time. After I see the quickstart folder, I go to bin and hit the start.bat the instance starts, but at the same time a file named as 'null' is created.

Below is a snapshot of the folder view.

Below is the content of null file if opened with text editor

Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Unrecognized option: --add-modules

The instance works fine though.

Anyone faced similar issue?

There were no modifications made when I started the instance and saw the null file.
