Missing basic JavaDoc for methods in Eclipse

Question

Today I installed the newest Eclipse IDE and I was wondering why it says "Note: The Javadoc for this element could neither be found in the attached source nor the attached Javadoc." when i hover with my mouse over the base methods / base classes. I googled for that problem and found a solution here: Missing basic JavaDoc in Eclipse . The given solution to set the location path to http://docs.oracle.com/javase/8/docs/api/ worked for me not 100%. The JavaDoc for the base classes eg java.lang.Thread is now displayed correctly, but I still get the missing JavaDoc message for any methods for example java.lang.Thread.start() .

Do you have any hints?

Even better than JavaDoc is to use a JDK (which includes the source code for core libraries). If your project is configured to use a JDK instead of a JRE, Eclipse will automatically detect and display both JavaDoc and source code for the core libraries. See https://stackoverflow.com/a/1157618/639520 for some details of setting up and using a JDK for your project.
