Stack trace not found in Output during Netbeans 7.4 debugging session

Question

In Netbeans 7.4, I set a breakpoint at the point where my program quit working and began debugging.

The first print statement printed; second didn't.

In the debugger, execution stopped here:

Even after I selected Continue ( F5 ) from the Debug pulldown, there was no stack trace in the output, so I was stumped about where the error actually occurred.

So I ran again but did NOT debug. I found a stack trace; problem easily solved.

Why didn't I get one while debugging? Is this just how it is in Netbeans when debugging?

As it happens, the exception was that availableLetters was null . I fixed the problem via the if statement below, but that doesn't answer my question:

转到菜单：Window-> Debugging-> Call Stack，然后它应该出现在自己的选项卡中，位于代码窗格下方。
