variables view & debugging jdk classes [message #306089]

hi !

I want to know if this is normal or if Im doing something wrong or if I have wrong settings or
wahtever...

when Im stepping through code in jdk classes during debugging, the variable view in degug
perspective shows me only values of class member variables and method parameters, I cant vire or
inspect local variables... This is very annoying... When I try to inspect or view such variable, I
get "<variableName> cannot be resolved"

I uploaded screenshot, there you can see that variable view shows me only "this" and "arg0" and
"arg1" (method parameters)...

Im using eclipse 3.2 final but I had this problem also with 3.1 if I remember well...

This question comes up every so often. The answer is that the rt.jar
that ships with the JDK (where the core Java classes live) is not
compiled with full debug information included in the .class files, so
the debugger does not have local variable info.

Unfortunately, this is not something that Eclipse can do anything about
- all debuggers will have the same problem with JDK core classes.

You could petition Sun to release a debug-enabled build of rt.jar, but
I'm sure lots of people have asked for it and I've yet to see any
official Sun response.

Hope this helps,
