The test JDK-8050964.js fails on plain Windows (no Cygwin installation) if %JAVA_HOME% contains a space. In particular, the following line in the test fails:

`${jdepsPath} -s -P ${nashornJar.absolutePath}`

The jdepsPath variable expands to a string containing spaces in this case. With %JAVA_HOME% set to C:\Program Files\Java\jdk1.8.0_45, the error is that the program "C:\Program" cannot be run.
