Show Supported Breakpoints
Select the Show Supported Breakpoints command [ ] to indicate if only breakpoints applicable to the current debug target should be visible in the Breakpoints View.
Example: If you have C/C++ and Java breakpoints, with this option turned on you will only see those breakpoints applicable to what you are currently debugging. Meaning that when you are debugging a Java program the Breakpoints View will only display Java breakpoints.
