SA does not dump debug info for scalar replaced objects in codecache dump:

 0xfa8d207b:    call	0xfa8ab060
static int test() @0xb65b3110 of public class sleep @0xb65b3160 @ bci = 18, line = 15
locals ([0], unknown scope value sun.jvm.hotspot.code.ObjectValue@9980d5) ([1], oop 0xb65b32b0) ([2], illegal) 
monitors (owner = oop 0xb65b32b0, lock = stack[16], normal) 
OopMap: 

Here is simple test:

public class sleep {
 int iii;
 public static void main(String[] args) throws Exception {
     int ii = 0;
     for (int i = 0; i < 2000000; i++) {
         ii += test2();
     }
 }
 static int test2() throws Exception {
     return test();
 }
 static int test() throws Exception {
     sleep sl = new sleep();
     synchronized (sleep.class) {
         sleep.class.wait(1);
     }
     return sl.iii;
 }
}

% java -XX:CompileThreshold=1000 sleep &
% pwd
<hotspot_rep>/agent/make
% sh clhsdbproc.sh <pid>
% dumpcodecache >ccdump.txt

Node: the instruction "dumpcodecache" will be implemented by this bug fix.

With the fix the dump will be:

0xfa8d207b:    call	0xfa8ab060
            static int test() @0xb65b3110 of public class sleep @0xb65b3160 @ bci = 18, line = 15

            monitors (owner = oop 0xb65b32b0, lock = stack[16], normal) 
            #ScObj0 sleep{ [iii :0]=#int 0 }
