Locally declared variables can not be inspected

Question

Sometimes when I am debugging code in Eclipse it happens that although I can see and inspect class member variables without any difficulty I am unable to inspect the values

Answer 1

I tried link (http://www.javaadvent.com/2014/12/recompiling-java-runtime-library-with.html), downloaded ant script and modified it. Modification: passed in javac. It generated rt.jar. Replaced rt.jar of JRE. (Don't forget to keep a backup).

Now I am able to watch, inspect local variables of any class in rt.jar during debug in eclipse.
