info threads 会显示所有线程吗？包括挂起的状态？

Info threads, also known as thread dumps or stack traces, are diagnostic tools that display the current state of all threads in a Java application, including their execution state, stack frames, and any blocked resources. They typically provide detailed information about the threads, such as their priority, status (e.g., running, waiting, suspended), and the call stack at the time the dump was taken[^1].

When you request an info thread from a Java environment, it will show all threads, even those in a suspended or waiting state. This can be useful for troubleshooting issues related to thread synchronization, deadlocks, or resource contention.

To view info threads in Java, you can use the `jstack` command-line tool, which is part of the Java Development Kit (JDK). For example:

jstack <pid> > thread_dump.txt

Where `<pid>` is the process ID of your Java application.
