Tomcat version: 8.5.72
org.apache.tomcat.util.threads.TaskQueue source code: https://github.com/apache/tomcat/blob/8.5.72/java/org/apache/tomcat/util/threads/TaskQueue.java#L33 In the comments of the TaskQueue class, it mentions "If you use a normal queue, the executor will spawn threads when there are idle threads and you wont be able to force items onto the queue itself.". But when we use java.util.concurrent.LinkedBlockingQueue, it will be put into the queue by default instead of creating threads. What queue does the normal queue in the comment refer to? Thanks, tianshuang
