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

It used to be that you can get debug rt.jar from http: //download.java.net/jdk6/binaries/, but not any more.

So building your own rt.jar with -g seems to be the only option now. It's very simple: just use javac and jar from your JDK.

• mkdir \tmp; mkdir \tmp\out
• Extract src.zip in JDK installation directory to tmp\src
• cd src
• find -name *.java > files.txt
• javac -verbose -g -d \tmp\out -J-Xmx512m -cp "\jre\lib\rt.jar";"\lib\tools.jar" @files.txt
• cd \tmp\out; jar cvf rt.jar *

If you use Eclipse, you don't need -Xbootclasspath/p:, instead just put your debug jar to Bootstrap Entries before JRE in launch configuration.
