Saptarshi De commented on LOG4J2-3235:
--------------------------------------
Hi [~rpopma]
We do not use BCEL. It might be a transitive dependency of tomcat 8.0.23.
We were using Log4j version 2.0.2 and had to update to 2.12.2 due to CVE. No
issues with version 2.0.2 its when we updated to 2.12.2 we are facing this
exception.
Please suggest.
