I just upgraded the Android Studio from Jellyfish to Koala. When the debugger reaches the breakpoint. I expanded all variables and got no values on them.

Here is some information about my environment:

When expanding the variables in debug pane. There are should be values on it. At least I got null when the variables has not been initialized. But I got nothing. All variable values are empty.
