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.

Log4j RCE Found
32 projects | news.ycombinator.com | 9 Dec 2021

Out of the box (at least on my text 1.8 JVM): corbaname, dns, iiop, iiopname, ldap, ldaps, rmi
For full details of how this works, use a vulnerable log4j version, log a simple (bad) lookup, and step through with a debugger for a while.
