很抱歉这篇长篇文章,但我想知道在我向 Sun 提交错误报告之前是否可以得到更多的关注。
JVM:6u11
操作系统:Windows XP SP3
硬件:AMD Athlon 64 X2 4600+ @ 2.41GHz,3.25 GB RAM。
我相信我在 JVM 中遇到了一个错误,没有为线程提供监视器。在以下线程跟踪中,监视器<0x12a8f9f8>
被 获取RelayedMessages-0000000001
,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夺监视器,但没有一个线程得到它。
我保证线程转储对于每个引用 monitor 的线程都是完整的<0x12a8f9f8>
。转储是使用 Java VisualVM 获得的,在 16 小时内 3 次,并且每次都显示是一致的(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,什么时候应该将它交付给其中一个?
