   When using jvm 17+ spark needs extra jvm args to avoid getting errors
   like
   ```
   [ERROR] Failed to execute goal 
org.codehaus.mojo:exec-maven-plugin:3.2.0:java (default-cli) on project 
comet-spark-spark3.4_2.12: An exception occurred while executing the Java 
class. class org.apache.spark.storage.StorageUtils$ (in unnamed module 
@0x35b75242) cannot access class sun.nio.ch.DirectBuffer (in module java.base) 
because module java.base does not export sun.nio.ch to unnamed module 
@0x35b75242 -> [Help 1]
   ```
   
   These args are already present inside the main pom.xml. To avoid
   duplicating the args we using maven to extract them. In order avoid
   slowing down the Makefile the args are defined as a function and
   therefore only evaluated when they are needed.
