While debugging Java code that uses reflection in Eclipse, some times I need to step into my invoked method or constructor. But reflection classes such as java.lang.reflect.Method and java.lang.Class do internal calls to sun.reflect.DelegatingConstructorAccessorImpl, sun.reflect.NativeConstructorAccessorImpl, sun.reflect.ReflectionFactory and others. These classes are not in the src.zip that is shipped with JDK.
This requires me to add sun.reflect.* to the debugger Step Filters. Otherwise I would have to press F5 (Step Into) multiple times in bytecode view, without any clue of when it will get into my code.
But being a curious person, I wish to know what’s going on. Someone please can tell from where can I download those sources, if such a link or repository exists?
from Oracle:
