@defaultMessage spawns threads with vague names; use a custom thread factory and name threads so that you can tell (by its name) which executor it is associated with

java.util.concurrent.Executors#newFixedThreadPool(int)
java.util.concurrent.Executors#newSingleThreadExecutor()
java.util.concurrent.Executors#newCachedThreadPool()
java.util.concurrent.Executors#newSingleThreadScheduledExecutor()
java.util.concurrent.Executors#newScheduledThreadPool(int)
java.util.concurrent.Executors#defaultThreadFactory()
java.util.concurrent.Executors#privilegedThreadFactory()

java.lang.Character#codePointBefore(char[],int) @ Implicit start offset is error-prone when the char[] is a buffer and the first chars are random chars
java.lang.Character#codePointAt(char[],int) @ Implicit end offset is error-prone when the char[] is a buffer and the last chars are random chars

@defaultMessage Only use wait / notify when really needed try to use concurrency primitives, latches or callbacks instead.
java.lang.Object#wait()
java.lang.Object#wait(long)
java.lang.Object#wait(long,int)
java.lang.Object#notify()
java.lang.Object#notifyAll()
