Thanks, Graydon.
You are right, we have finally removed the static -Xmx setting to let the JRE decide how much RAM to assign (in many cases, it will now be more than 2GB – usually 25% of the available main memory).
As described in the documentation, it is still possible to assign Java flags to the BASEX_JVM variable.
Cheers, Christian

Excellent news!
I notice that the
# Options for virtual machine (can be extended by global options)
BASEX_JVM="-Xmx16g $BASEX_JVM"
line is gone, it seems generally, from the startup scripts.
https://docs.basex.org/main/Start_Scripts continues to reference setting -Xmx.
Is there a new place to do this or is it expected to not be required with 12?
Thanks! Graydon
