Eclipse debugging “source not found”

by

I had this very annoying problem for a long time but was finally able to solve it. In my case, a null pointer exception was being thrown somewhere in Java’s Transformer.IsRuntimeCode(ProtectionDomain) function.

I didn’t really need to know about this since the exception was being caught and handled, but eclipse would pause debugging every time this happened and tell me that the source wasn’t available. As a result, I constantly had to keep pressing the button to continue code execution.

In order to prevent this from happening, I:

  1. Clicked on the “Breakpoints” window
    at the bottom of the debugging
    screen
  2. Right clicked “NullPointerException”
  3. Unchecked “Caught”

This prevented the debugger from pausing program flow during a caught NullPointerException.
