I am defining each of the Environment Variables in an <Environment> Tag inside
of the context.xml like:
<Context>
...
<Environment name="email.abc.signup.subject" value="Sign Up for the ABC Plan"
type="java.lang.String" override="false" />
...
</Context>
I am getting an nullpoint exception when doing something with information
returned from Context.lookup("java:comp/env/EnvironmentVariables") method here
is the exact stack trace:

What is the full stacktrace of the error in the logs?
