Errors in Eclipse as reported by Alexandre Vermeerbergen

First set of errors is very strange: in /storm-cassandra/src/test/java/org/apache/storm/cassandra/trident/WeatherBatchSpout.java,
 
I have these imports:

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Random;
import java.util.UUID;

with all the same errror: "The package java.util is accessible from
more than one module: <unnamed>, java.base"
=> this look like an issue with the notion of Java modules
