We've looked for "log4j" in the NetBeans 12.6 binaries, as follows:

--
nb16$ find . -type f | grep -i log4j
./extide/ant/lib/ant-apache-log4j.jar
./ide/modules/ext/log4j-1.2.15.jar
--

So, we ship "log41-1.2.15.jar" with the binaries and, quoting the official
source [1]:

"Log4j 1.x is not impacted by this vulnerability."

(where "this vulnerability" means
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-44832).

Hope it helps,

Gj
