I’m using the Eclipse IDE for Java EE Developers (Mac OS X 64 Bit) to debug my two java documents. I have a Name class with a method named insert. It executes but gives wrong result. NamesTester is test class for Name class.
During debug, when I using step into the insert method, it jumps to a strange document named ArrayList<E>.size(), and it shows Source not found. I don’t know what’s wrong. Does it means I can not step into a method to see what is happening there? But if I use step over, it’s debugging next steps fine.
Can someone help me in finding the reason and solution? Thank you!
It means you jumped into a class definition your project classpath has no access to. For example Java JVM source code.
In your case, perhaps it tried to jump into ArrayList definition.
Look out thru google about debugging in eclipse, step into and step thru
