Figure 2–1 Class Loader Runtime Hierarchy The following table describes the class loaders in the Application Server. Class Loader Description Bootstrap The Bootstrap class loader loads the basic runtime classes provided by the JVM, plus any classes from JAR files present in the system extensions...
The returned array may contain more than one Package object of the same package name, each defined by a different class loader in the class loader hierarchy. API Note: The platform class loader may delegate to the application class loader. In other words, packages in modules defined to the ...

在JVM中,class是用类全名(包名+类名) 再加上加载这个类的classLoader来唯一标识的,例如class的类全名是C1,classLoader是L1,那么这个class instance在JVM中的key就是(C1, L1),此时另一个classLoader L2也加载了该类,那么将会有另一个class instance (C1, L2),这两个class instance是不同的type,如果这两个clas...
