Steps to reproduce the problem:
1. Set a breakpoint and stop at that breakpoint.
2. Use Debugger.evaluateOnCallFrame to change a local variable name, say "aaa = 3";
3. Issue a Runtime.getProperties request to check the current local variables on the stackframe. 
4. Saw that the returned value for "aaa" is still the old value.

Logs:

What is the expected behavior?
I expect to see {"name":"aaa","value":{"type":"number","value":3,"description":"3"}

from the returned call.

What went wrong?
The local variables on the stack frame are not updated, unless I release the runtime (resume from breakpoint), which means if I step over or continue, the variable is actually updated and effective.

Did this work before? No
