FWIW we have been using OpenJDK (installed from Ubuntu repositories) to
run web applications using Groovy in production for years without any issue.

Hi,
It used to be the case that OpenJDK and OracleJDK had quite a few
differences in terms of performance and compatibility. But that is no
longer the case in my experience & should be no technical differences
in the near future:

In fact many IaaS platforms can only run OpenJDK due to licensing - so
if you're running Grails on AWS Elastic Beanstalk you're already using
OpenJDK (which we do).
Since AWS uses OpenJDK I've been using Azul on my Mac (via sdkman) for
quite some time and have not noticed any incompatibilities or
differences when running Grails or other small groovy apps/scripts.
With Oracle's new release cadence and no overlapping support
timelines[2] - I don't see how any non-oracle-paying java users could
use anything but OpenJDK. For me I don't want to spend time upgrading
my JDK - would rather ship customers features :)
Just my 2c & experience,
-Eric
PS: Maybe worth reaching out to Azul and asking what tests they did to
mention Scala - and to add Groovy there too :D

Hi,
I would be interested to hear if anyone has experience with using
alternative JVMs with Groovy, especially Azul
(https://www.azul.com/) ?
Licensing costs for long term OpenJDK support seem to be much
lower, and the JVM has additional benefits such as an elastic
memory model (JVM memory is dynamically allocated/deallocated from
the os), continuous concurrent garbage collection without
freeze-the-world fallback, and application startup (warmup) time
improvements.
But I am worried about Groovy compatibility (they only mention
Scala explicitly on the web page)...
Cheers,
mg
