During the install process, jpy may error out with
Error: environment variable "JAVA_HOME" must be set to a JDK (>= v1.7) installation directory
This is a confusing error message when JAVA_HOME is set, see https://github.com/jpy-consortium/jpy/issues/106. In this case, the "lib" source directory was missing. It would probably be prudent to error out with a more explicit error message when one of the java home environment variables is set and either the directory doesn't exist, or the directory exists but the needed subdirectories don't exist.
