Ralph Goers commented on LOG4J2-3622:
-------------------------------------
See https://github.com/alexcheng1982/jdk-loom-faq "Can thread local variables
be disabled for virtual threads?". It appears they are NOT disabled by default.
However, we need to check if ThreadLocals are disabled and use alternate
mechanisms when they are.
