--- Comment #10 from Alex Macdonald <almac...@redhat.com> ---
I've updated the package to be latest (2.4.10) instead of 2.3.2. I've included
a link to the spec and the SRPM below.

Spec URL:
https://src.fedoraproject.org/fork/almac/rpms/mvel/blob/master/f/mvel.spec
SRPM URL:
https://download.copr.fedorainfracloud.org/results/almac/lz4-java/fedora-33-x86_64/01744942-mvel/mvel-2.4.10-1.fc33.src.rpm

Having said this, there was an issue with updating to this version of mvel;
lz4-java builds started failing due to improperly formatted generated code [0].
There appears to be an issue in mvel as of version 2.4.0 (related issue: [1]),
where new lines are not being included when generating the files. The resulting
code is written on a single line, which causes problems when the templates
contain comments because it invalidates the rest of the code. As a preventative
measure I've patched out the comments in the lz4-java mvel templates [2], which
allows this version of mvel to work with lz4-java 1.7.1 [3].
