我实现了一个未捕获的异常处理程序来捕获未捕获的异常。但在某个时间或某些设备上，此处理程序失败 java.lang.StackOverflowError . 以下是异常日志：

以及导致错误的线路 defaultUEH.uncaughtException(t, e); stacktrace说。
完整代码是：

import java.lang.Thread.UncaughtExceptionHandler;
import android.util.Log;

class CustomExceptionHandler implements UncaughtExceptionHandler {

private UncaughtExceptionHandler defaultUEH;

protected CustomExceptionHandler() {
    try
    {
        this.defaultUEH = Thread.getDefaultUncaughtExceptionHandler();
    }
    catch(Exception e)
    {
        System.out.println("Exception: "+e);
    }
}

public void uncaughtException(Thread t, Throwable e) {
    try
    {
        String stacktrace = Log.getStackTraceString(e);

        SendStackTraceToServer sendStackTraceToServer = new SendStackTraceToServer();
        sendStackTraceToServer.startThreadToSendRequest(stacktrace);

        defaultUEH.uncaughtException(t, e); // this line cause stackoverflow error.
    }
    catch(Exception ex)
    {
        System.out.println("Exception: "+ex);
    }
}

protected static void setDefaultUncaughtExceptionHandler()
{
    Thread.setDefaultUncaughtExceptionHandler(new CustomExceptionHandler());
}
}

帮我解决这个问题。因为我无法复制这个问题（或者我不知道如何复制这个问题）。
