      Because the class is deliberately unsychronized, the buffer pool could be null after it has been checked for null, resulting a NPE like the one we are seeing in CI failure (UNDERTOW-2400):

      Error:  testAsyncRespondBeforeRead(io.undertow.servlet.test.response.writer.ResponseWriterTestCase)  Time elapsed: 113.969 s  <<< ERROR!
