I just upgraded to Eclipse Juno but I found there is no debug toolbar (Resume/Step into/Step over/Stop etc.) in Debug perspective?? How can I find the toolbar back? Thanks!<
In Debug window there is this drop down menu (indicated by small rectangle) check the option "Show Debug Toolbar", that was the problem in my case
Here's where you find the menu to turn it back on:
Make sure they're checked in the 'Customize Perspective' dialog under toolbar visibility and Command Groups Availability.
In case of Kepler eclipse version, debug toolbar can be made visible using Eclipse->Window->Show Toolbar
