    Description

      After a chronic bout of OutOfMemoryError in our development environment, a heap analysis is showing that more than 10G of our 12G heaps are consumed by the threadLocals members (instances of java.lang.ThreadLocalMap) of various io.netty.util.concurrent.FastThreadLocalThread instances. Reverting cecbe17 fixes the issue.
