Searching the web for that "Could not reserve enough space in CodeHeap
'non-nmethods' (2496K)" message turns up
<https://github.com/AdoptOpenJDK/openjdk-build/issues/1130> "MacOS hardened
runtime support".  It mentions a
com.apple.security.cs.disable-executable-page-protection key set to true, a
setting which our
<https://git.libreoffice.org/core/+/2c366aae9263dc4115b054fe74b90cabea61fa0b%5E%21>
"Use a less extreme entitlement for our run-time machine code generation"
appears to have dropped from hardened_runtime.xcent.in starting with LO 7.0. 
So that commit might be related.
