Fixed version (ground truth):
@Override public void handle(Command command,Arguments arguments,Response response,IDebugAdapterContext context){
  StackTraceArguments stacktraceArgs=(StackTraceArguments)arguments;
  List<Types.StackFrame> result=new ArrayList<>();
  if (stacktraceArgs.startFrame < 0 || stacktraceArgs.levels < 0) {
    response.body=new Responses.StackTraceResponseBody(result,0);
    return;
  }
  ThreadReference thread=DebugUtility.getThread(context.getDebugSession(),stacktraceArgs.threadId);
  int totalFrames=0;
  if (thread != null) {
    try {
      totalFrames=thread.frameCount();
      if (totalFrames <= stacktraceArgs.startFrame) {
        response.body=new Responses.StackTraceResponseBody(result,totalFrames);
        return;
      }
      List<StackFrame> stackFrames=stacktraceArgs.levels == 0 ? thread.frames(stacktraceArgs.startFrame,totalFrames - stacktraceArgs.startFrame) : thread.frames(stacktraceArgs.startFrame,Math.min(totalFrames - stacktraceArgs.startFrame,stacktraceArgs.levels));
      for (int i=0; i < stackFrames.size(); i++) {
        StackFrame stackFrame=stackFrames.get(i);
        int frameId=context.getRecyclableIdPool().addObject(stackFrame.thread().uniqueID(),new JdiObjectProxy<>(stackFrame));
        Types.StackFrame clientStackFrame=convertDebuggerStackFrameToClient(stackFrame,frameId,context);
        result.add(clientStackFrame);
      }
    }
 catch (    IncompatibleThreadStateException|IndexOutOfBoundsException|URISyntaxException|AbsentInformationException e) {
    }
  }
  response.body=new Responses.StackTraceResponseBody(result,totalFrames);
