Today is a bad day to run a VMWare cluster with thousands of java apps.
I'm not sure what you mean. You can deploy a built binary over your network and run it on all your servers. For example: curl -sSL https://github.com/1lann/log4shelldetect/releases/download/v0.0.2/log4shelldetect_0.0.2_Linux_x86_64.tar.gz | tar -C /tmp/ -zxf - log4shelldetect && /tmp/log4shelldetect -mode list /path/to/scan 2>/dev/null would download and extract the prebuilt binary to /tmp, and run it scanning at /path/to/scan, only outputting paths to potentially vulnerable .jars and ignoring warnings. You can replace the URL with your own build or distribute your own build as you wish.

Log4j RCE Found
Are there any mitigations in recent JVMs?
I tried reproducing this, and got the POC to hit the LDAP server, but it wouldn't load the test payload.
