I found that when tracing JRE source code in eclipse, I can't see variable values. Is it possible to see them somehow?
EDIT
The answer was to rebuild rt.jar
. Just attaching JDK sources is not sufficient.
Do you mean debugging java code ? if so if you set a breakpoint a debugger should stop there and you are going to see all variables in a current context. You can even mouseover your source code to see values
