I can think of two possible reasons you are seeing Compiled Code
instead of line numbers.
1) you need to compile with the option that leaves line number
information in the .class file. See the compiler options in the
tooldocs.
2) you need to run without the JIT compiler because it discards
line number information. Try setting the environment variable
set JAVA_COMPILER=NONE
