      When Undertow is shutting down, somethings we see the following stack trace:

      java.lang.NullPointerException: Cannot invoke "Object.equals(Object)" because "threadLocalData" is null
              at io.undertow.core@2.3.14.Final//io.undertow.server.DefaultByteBufferPool$ThreadLocalCache.remove(DefaultByteBufferPool.java:360)

      The stack trace is taken from a WildFly shutdown, but notice that this error can come up in standalone mode as well, when shutting Undertow.
