Both https://github.com/ITArray/automotion-appium-example and https://github.com/ITArray/automotion-selenium-example examples hang when executing uiValidator.generateReport method. After the hanging, the CPU load by Java process is increased to about 30% and then remains until the Java process killing. No reports are generated.
It does not matter whether the test launched via Maven or via IDE. It does not matter which Windows 10 edition(Home or Pro) is used.
Note that the same noticed examples work smoothly on Ubuntu 16.04 LTS, so it seems to be an OS-depended bug.
