NullPointerException when running Android "Screenshot2"

[mkm12789]

When stepping through the failing bitbar image recognition demo I notice I'm getting the following error when running the command line screenshot2 app for android:

Exception in thread "main" java.lang.NullPointerException
at com.android.ddmlib.MonitorThread.wakeup(MonitorThread.java:453)
at com.android.ddmlib.MonitorThread.quit(MonitorThread.java:461)
at com.android.ddmlib.AndroidDebugBridge.terminate(AndroidDebugBridge.java:293)
at com.android.screenshot.Screenshot.main(Screenshot.java:280)

I'm using version 26.1.1 of Android SDK tools and JDK 8u151

Has anyone experienced this?

Do you have it in android-sdk/tools/bin/ ? If so it should be enough to add it to the PATH.
It can be also installed (for Ubuntu):
sudo apt install android-platform-tools-base
