PURPOSE: A device and a method for synchronizing a multi threads system of a JVM(Java Virtual Machine) are provided to increase the concurrency of the system by subdividing a unit of a lock used to realize the
Of all the various means of synchronization in the JVM, the most sophisticated is actually that of the class loader. Whenever a thread refers to a class encountered for the first time, some relatively complex logic kicks in to ensure that two threads don't simultaneously try to load and/or...

To that end, this object contains the SyncItem thread management method. All it does is starts the synchronizing process for each SyncItem object. At one point, I had planned on using the SmartThreadPool similar to the code in this article, but decided later on that I didn't really need...
constant Timer的使用 1.主要作用是设置固定时长,单位为毫秒 2.定时器的作用范围可以是整个thread group,也可以是单个的sampler(采样器),若是作用于某一个sampler,则作为它的子节点。 3.定时器执行顺序是在每个sampler之前执行的,而不是之后(不管定时器的位置在sampler之前还是下面) 当full join结果插入一张表执行...
