I can certainly reproduce, but it works if I remove the quotes.

> set JAVA_HOME="C:\Program Files\Java\jdk1.8.0_121"

> jython --print
"\"C:\Program Files\Java\jdk1.8.0_121\"\bin\java" -Xmx512m -Xss1024k -classpath C:\jython\2.7.1rc1\jython.jar;. -Dpython.home=C:\jython\2.7.1rc1 -Dpython.executable=C:\jython\2.7.1rc1\bin\jython.exe -Dpython.launcher.uname=windows -Dpython.launcher.tty=true org.python.util.jython

Notice the questionable use of quotes? Tidy them up and it runs.

And similarly, if you define the variable without them:

> set JAVA_HOME=C:\Program Files\Java\jdk1.8.0_121

> jython

I know it's quite common to quote paths in environment variables or scripts, especially if there are spaces invoilved, but this time it works against you. If we wanted to be resilient to this kind of thing (#2346), maybe we'd strip them in the launcher before composing the path?
