Exception in thread "main" java.lang.SecurityException: Prohibited package name: java.test.list

原因:定义包时不能以java.的形式定义

测试代码如下:

package java.test.collection;

public class ArrayListTest {

	public static void main(String[] args) {

		System.out.println("test java package");
		
	}	
}

异常如下:

Exception in thread "main" java.lang.SecurityException: Prohibited package name: java.test.collection
