Jvm 当java.lang.Thread.State被阻塞时，如何获取对象监视器地址？

jvm

Jvm 当java.lang.Thread.State被阻塞时，如何获取对象监视器地址？,jvm,Jvm,我们发现应用程序存在阻塞问题，从堆栈转储中我们发现许多线程（其中一个是catalina-exec-998）被线程catalina-exec-995通过锁0x000000065888b918阻塞，并且我们还发现阻塞线程catalina-exec-995也处于阻塞状态，它似乎试图获取另一个线程已经拥有的对象监视器，但是在堆栈调用中没有关于它试图等待的对象监视器地址的信息所以我的问题是如何找到它等待的对象监视器\lock地址另外顺便说一句，如何防止对象监视器被JIT编译，以使等待信息始终由JVM选

我们发现应用程序存在阻塞问题，从堆栈转储中我们发现许多线程（其中一个是catalina-exec-998）被线程catalina-exec-995通过锁0x000000065888b918阻塞，并且我们还发现阻塞线程catalina-exec-995也处于阻塞状态，它似乎试图获取另一个线程已经拥有的对象监视器，但是在堆栈调用中没有关于它试图等待的对象监视器地址的信息

所以我的问题是如何找到它等待的对象监视器\lock地址另外顺便说一句，如何防止对象监视器被JIT编译，以使等待信息始终由JVM选项-XX:CompileCommand可用
顺便说一句，我在中也发现了类似的问题，从JVM专家的回答中，我知道缺少的“等待”信息可能是由JIT编译器造成的，该URL中的解决方案仅适用于同步对象中的Object.wait（），但是我的情况明显不同，因为它试图获取对象监视器，而不是等待从同步对象获取通知
以下信息是所提到的两个线程的调用堆栈：
