Doc from org.graalvm.polyglot.io.ProcessHandler.start.

A request to start a new subprocess with given attributes.

The default implementation uses ProcessBuilder to create the new subprocess. The subprocess current working directory is set to ProcessCommand#getDirectory(). The ProcessCommand#getDirectory() value was either explicitely set by the guest language or the FileSystem's current working directory is used. The subprocess environment is set to ProcessCommand#getEnvironment(), the initial value of ProcessBuilder#environment() is cleaned. The ProcessCommand#getEnvironment() contains the environment variables set by guest language and possibly also the JVM process environment depending on value of Builder#allowEnvironmentAccess(org.graalvm.polyglot.EnvironmentAccess).
