Maybe it is a side effect of deleting `initJFrameCache()` from PStack.java.
I do not have Mac, so I cannot verify the following...

`BsdDebuggerLocal::threadList` would be filled in `getJavaThreadsInfo()`, and it is eventually called through a chain of calls starting from `BsdThread::getContext()`. It is eventually called by `getCurrentFrameGuess()` from `PStack::initJFrameCache()`.

I think it is better to separate BsdDebuggerLocal::getJavaThreadsInfo() - filling threadList can move to getThreadList() because it is not needed in getJavaThreadsInfo().
