很抱歉发了这么长的帖子，但我想知道在我向Sun提交bug报告之前，我是否可以获得更多的关注。

JVM: 6u11

操作系统: Windows XP SP3

硬件: AMD Athlon 64 X2 4600+ @2.41 GB，内存3.25 GB。

我相信我在JVM中遇到了一个错误，没有给任何线程一个监视器。在下面的线程跟踪中，RelayedMessages-0000000001获取了监视器<0x12a8f9f8>，并最终等待它；随后通知了该线程。然而，即使列出的所有线程都在争用监视器，但没有一个线程获得它。

我保证对于每个引用监视器<0x12a8f9f8>的线程，线程转储都是完整的。转储是使用Java VisualVM获得的，在16个小时内获得了三次，并且每次都是一致的(这些线程没有变化)。

有没有人不同意我的评估，即JVM未能将监视器交付给任何符合条件的线程，而它应该将监视器交付给其中一个线程？

所提供的线程跟踪相对于所讨论的锁是完整的。与我共事的另外两个人也同意，JVM错误已被明确指出，jProfiler (ej-technologies)的程序员也是如此。
