Vivek commented on LOG4J2-3390:
-------------------------------

[~ggregory]  : Yes, We have implemented 2.17.1 bridge api in our new 
microservices. Services running with Java8+ are working fine. But we do have 
some legacy applications which are running on java6 and due to server's end of 
life we are not able to upgrade Java version here. We are looking for solution 
which can work with java 6.

> Currently log4j1 is being used in our application with Java1.6 but due to
