------------------------------------------------------------------------
another source of entropy is
"src/resources/org/apache/cassandra/config/version.properties" where it had
header where timestamp was changing as it contained the date when it was
generated.
If a static header is used, as shown below, with comment like that
{code}
<propertyfile file="${version.properties.dir}/version.properties"
comment="Auto-generated, do not modify!">
<entry key="CassandraVersion" value="${version}"/>
<entry key="GitSHA" value="${git.sha}"/>
<entry key="BuildDate" value="${build.date}"/>
</propertyfile>
{code}
then I got the same jars when it comes to their sizes for the first time, but
their content seem to be still somehow re-ordered.
same-file-sizes-inside-bin-tarball.html shows that.
