**What would you like to be improved?**
In server/src/main/java/org/apache/gravitino/server/GravitinoServer.java,
the main method could throw an ArrayIndexOutOfBoundsException if the
GRAVITINO_TEST environment variable is set but args is empty.
**How should we improve?**
Check if args.length < 1 and log an error, then exit safely.
```java
String confPath = "";
if (System.getenv("GRAVITINO_TEST") != null) {
if (args.length < 1) {
LOG.error("Missing argument for GRAVITINO_TEST conf path.");
System.exit(1);
}
confPath = args[0];
}
```
This ensures that even if GRAVITINO_TEST is set and args is empty, no
exception will be thrown.
Fixes #8305
