Show return value of a method #660

Hi, below I describe the issue, but it's basically in the title. Like in other debuggers I'd like to see this implemented.

Environment

• Operating System: Windows 10 Pro Build 17763
• JDK version: 8
• Visual Studio Code version: 1.38.1
• Java extension version: Java Extension Pack 0.8.0
• Java Debugger extension version: 0.21.0 - 2019-08-26

Steps To Reproduce

1. Start a debug session
2. Step into a method with a return value.
3. Step forward till the return statement.
4. Return or step out to the calling method.

Current Result

The return value of the returning/stepped out method is not shown in the debugger side window.

Expected Result

To see somewhere the return value of the returning/stepped out method.
