My Arduino 1.6.3 cannot detect port

Just tried the new released Arduino IDE 1.6.3 on Ubuntu Linux 14.04, the first time run is ok.

But after a moment, it cannot detect connected usb port, with error following error. Even after reboot.
~/arduino-1.6.3$ ./arduino
Exception in thread "cc.arduino.packages.discoverers.serial.SerialBoardsLister" java.lang.NullPointerException

Tried to switch back to Arduino 1.6.0, it can detect usb as normal.
