[Geoserver-users] Outdated log4j 1.2 in 2.23.1 distribution

Hello, everyone!

I’ve been working on cleaning out old versions of Log4j on my servers, and I just discovered that the latest Geoserver “Platform Independent Binary” (v2.23.1) is still shipping with log4j 1.2 bundled in, even though it also includes log4j 2.17.2 and the bridge configuration. I’m guessing this may be some kind of packaging error; deleting the old log4j 1.2 jar does not seem to have interfered with the operation of my instance.

I tried to access the issue tracker to see if anyone else had reported this, but I had trouble getting in – apologies if I made a newbie error somewhere, or if I’m misunderstanding what I’m seeing. In any case, I just thought someone in the community might want to know about this!

And here’s some evidence to demonstrate what I’m seeing – my command line from this morning when I downloaded a fresh .zip file and confirmed that the extra log4j jar still seems to be in there:

$ wget https://sourceforge.net/projects/geoserver/files/GeoServer/2.23.1/geoserver-2.23.1-bin.zip

I hope this is helpful!

Hi,
yes, it’s an assembly leftover, as far as I know, you can safely remove it.
See also:

(the Windows binary is based on the bin package, hence, they both contain that same extra file)

Cheers
