Eclipse IDE for Java Developers Version: Luna Service Release 2 (4.4.2) Build id: 20150219-0600 I put some breakpoints in this first picture:

After that, i clicked the bug symbol to start debug mode:

But the application started as if it is in normal run mode. And as you can see in 2. picture, those buttons can not be clicked (next step, step into).
I was using kepler, it was same so i downloaded luna but it is still same. I could use debug mode 5-6 months ago. I did not use eclipse since that time and did not change anything.
