My JDK version is 1.6.03
In the class ThreadPoolExecutor, the counter for completed tasks, long completedTaskCount, with the line 1007:
completedTaskCount += w.completedTasks;
will increase forever if the instance of ThreadPoolExecutor keep alive. It's never reset.
We know that the thread pool usually run as a long time task, so the variable long completedTaskCount is easy to overflow, especially for the heavy load application. We really don't know what will happen if it overflow.
So, this class should be rewritten for the more robust application.

About Mo Gan Mountain
登莫干山记
是岁十月有遐，乃往浙之莫干。霜露其时，薄凉侵衣。从德清买车登山，道既迂曲，木亦森然，竹植处处，与游风相激，有瑟瑟声。至山中，饮宿客馆，稍醺。乃划然长啸，乘兴踏青。已而暮色四合，寻壑经丘，影影绰绰而已。悄然失志，归寝。
次日游皇后别墅松月楼白云山馆等处，筑皆依岩，设不同俗。剑以名山，寒以著泉。木石凛凛，劲然虬然。山人云，此地曾有江山美人，英雄豪杰，无边松月，快哉天风；然百年兴废，一言难尽；春秋旧事，莫问是非！唯山中雾竹，与岩上泠泉，能结往古之翠，可传千岁之寒也。
骋目四顾，万顷所如。风波不兴，照日和煦。时有林禽，往来幽鸣：声也嘤嘤，迹亦盈盈；纤纤红叶，翩翩幽篁。岂非武陵故地，世外桃源邪？怅留久之。沧桑如此，能无慨乎？既往悠悠兮，江山如梦；今夕何夕兮，风月殊异。是为记。
