openjdk11-bootstrap fails to install as a non-root user

I have to install and run macports as a non-root user on a work laptop. The port openjdk-bootstrap fails because it tries to create a folder in /Library instead of the user's library folder. Specifically,

How would you suggest to fix this? Java must be installed into /Library/Java/JavaVirtualMachines in order to work.

Why is that? Isn't it enough for 'java' and 'javac' to be in the PATH? Are you saying that java can't be installed in a custom location on a mac?

To be completely clear, openjdk-bootstrap got pulled in when I tried installing pdftk-java. I actually already have java installed in /Library/Java/JavaVirtualMachines. Is there any way to tell macports to just use that instead of trying to install openjdk-bootstrap?
