I get that error when I attempt to start the Glassfish server 4 at localhost[domain1]
Unable to start server due to following issues: Key value shall not be null.
I could not find a solution.
Thank you.
This seems to be a configuration issue:
As mentioned in this post you have to change two of your config files:
In the Glassfish domain.xml (located in glassfish\domains\%domainname%\config) find the section <java-config in the <config name="server-config"> section and add the following line into it:
-Duser.language=en
In the eclipse.ini (located in your root folder of your eclipse installation) add the following line at the end:
-Duser.language=en
