Plenty of other software is already doing this (e.g. Atlassian JIRA
which is very well known and has hundreds of plugins). Oracle's main
intent is to prevent redistributing of a public JRE without their
consent, where "public" means a JRE used to run system-wide applications.

According to
http://www.oracle.com/technetwork/java/javase/jre-8-readme-2095710.html:

"When redistributing the JRE on Microsoft Windows as a private
application runtime (*not accessible by other applications*)"

(Emphasis is mine) Whether it's user code running on it or not, it's
still running as part of Postgresql so it's a private JRE.
