Tomcat线程正在等待并锁定相同的资源

Question

考虑以下Java \ Tomcat线程转储：

"http-0.0.0.0-4080-4" daemon prio=10 tid=0x0000000019a2b000 nid=0x360e in Object.wait() [0x0000000040b71000]
   java.lang.Thread.State: WAITING (on object monitor)
    at java.lang.Object.wait(Native Method)
    - waiting on <0x00002ab5565fe358> (a org.apache.tomcat.util.net.JIoEndpoint$Worker)
    at java.lang.Object.wait(Object.java:485)
    at org.apache.tomcat.util.net.JIoEndpoint$Worker.await(JIoEndpoint.java:458)
    - locked <0x00002ab5565fe358> (a org.apache.tomcat.util.net.JIoEndpoint$Worker)
    at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:484)
    at java.lang.Thread.run(Thread.java:662)

这是僵局吗？看来，同样的资源（0x00002ab5565fe358）既locked和waited on-这是什么意思？

Answer 1

它更像是无限的 wait()。它会说类似 id1 在 id2 拥有的监视器上被阻止
