A breakpoint suspends the execution of a program at the location where the breakpoint is set.

Breakpoints can be enabled and disabled via the context menu in the Breakpoints View , or via the context menu in the Java Editor ruler.

  • An enabled breakpoint causes a thread to suspend whenever the breakpoint is encountered. Enabled breakpoints are drawn with a blue circle [ Breakpoint ] and have a checkmark overlay once successfully installed. A breakpoint can only be installed when the class the breakpoint is located in has been loaded by the VM.
  • A disabled breakpoint will not cause threads to suspend. Disabled breakpoints are drawn with a white circle [ Disabled Breakpoint ].

Breakpoints are displayed in the vertical editor ruler and in the Breakpoints view.
