The example simple_plot.py works with Java 11, but throws a warning

[pmi123]

I tested orhelper using simple_plot.py, OpenRocket 15.03 and Open JDK 11, and it worked. However, it generated these warnings:

2022-11-02 18:23:25] INFO [orhelper._orhelper.__enter__:48] Starting JVM from /usr/lib/jvm/java-11-openjdk-amd64/lib/server/libjvm.so CLASSPATH=OpenRocket-15.03.jar

It might not be related to Orhelper, but I thought I would pass it along.
