Cassandra 3.11.7 on Ubuntu 20.04 doesn't seem to pick up the jemalloc library?

apt shows:

libjemalloc2/focal,now 5.2.1-1ubuntu1 amd64 [installed]

Cassandra logs:

jemalloc shared library could not be preloaded to speed up memory allocations

The same version of Cassandra on Ubuntu 18.04 picks up libjemalloc2 just fine, there a trick to getting it to work on 20.04?

It might be this issue:

bin/cassandra" only looks for "libjemalloc.so" or "libjemalloc.so.1" which doesn't match our "libjemalloc.so.2

So then try to create a symlink

libjemalloc="$(readlink -e /usr/lib/*/libjemalloc.so.2)"; \
ln -sT "$libjemalloc" /usr/local/lib/libjemalloc.so; \
