Francesca Merighi commented on LOG4J2-817:
------------------------------------------

I'm sorry for my late answer.

My environment:

Linux 	2.6.32-431.17.1.el6.x86_64 

JVM 1.6.0_32-b32 (OpenJDK Runtime Environment (IcedTea6 1.13.4) (rhel-7.1.13.4.el6_5-x86_64), OpenJDK 64-Bit Server VM (build 23.25-b01, mixed mode))

Apache Tomcat/6.0.24

I've never still tried to build from master branch, i'll try in the next weeks.

Thanks.
