在同步块java / android中抛出异常

在遇到同步块时，我遇到了一些奇怪的事情 . 我有一个需要在同步块内的缓存 . 块内发生异常，由于某种原因不会进入catch块 . 我试过调试它，我看到它调用了InvocationTargetException构造函数然后它转到ThreadGroup uncaughtException（Thread t，Throwable e）方法 .

我有一个try catch围绕synchronized块，事实上还有另一个内部try-catch覆盖了异常发生的代码行...

有谁知道为什么它没有到达catch块？

我甚至试图尝试捕获InvocationTargetException以及Exception，并且正如预期的那样，它不会编译，因为内部没有任何东西抛出这种异常 . 我确实理解异常的原因，但我担心的是它没有被 grab 并杀死线程 .

@Override
public void onLocationChanged(Location loc) 
{
    if(lastKnownLatitude != null && lastKnownLongitude != null)
    {
            try
            {

                synchronized (dataManager.getRegisteredGeo()) {for(String geoName : dataManager.getRegisteredGeo().keySet())
                    {
                        GeoNotification geoNotification = dataManager.getRegisteredGeo().get(geoName);
                        boolean isInside = geoNotification.isLocationInsideFence(loc.getLatitude(), loc.getLongitude());


                        geoNotification.setLastKnownDeviceInside(isInside);
                        GeoUpdateMsg updateMsg = new GeoUpdateMsg(geoNotification.getTransactionId());
                        updateMsg.sendData(updateMsg.serializeObjectIntoXml());

                    }   
                }
            }
            catch(Exception e)
            {
                Logger.LogError("Exception while processing  geo notifications" + e.getMessage());
            }
    }
}

这是设备位置更改时触发的事件

这是我从log cat获得的，没有捕获异常
