Debugging step buttons disabled in Eclipse Oxygen

Question

I have upgraded Eclipse to Oxygen, with Scala and Python added. I noticed that when programming in Java, the step commands of the debugger remain disabled. I can run the debugger, and it will run until it hits a breakpoint, but then i cannot step in or over. I can only stop the (local) VM.

Any thoughts?

In the _Debug_ view, make sure you have selected a thread that is paused by a breakpoint, not a running thread (the step commands refer to the selected thread). — howlger, Sep 21 '17 at 14:45
Could you please add a screenshot of the _Debugging_ perspective to your question? — howlger, Sep 22 '17 at 07:35
Can you check Debugger timeout(ms) value. The field is available Preferences---> Debug---> Communication. — Shahbaz Ahmad, Dec 16 '17 at 10:57
Same problem with Eclipse Oxygen 4.7.1a, trying to debug an application running in JDK 7. The problem disappears when debugging the application with JDK 8. — Lolo, Dec 18 '17 at 10:56
The application I am debugging has 100+ threads. Is there a reason Eclipse could not have automatically selected the thread where the breakpoint was hit? I had to hunt for it and select it. — froggythefrog, Dec 27 '18 at 20:52

In my case increasing the "debug timeout" value resolved the problem. Thanks to @Shahbaz Ahmad comment.

Preferences >> Debug >> Connection Timeout

If you have all code in main function then put a breakpoint at main function as well. And if you have multiple functions, breakpoint on methods as well ( if you have breakpoint inside that method).

Basically, put a breakpoint on the function in which you have added breakpoints.
