Differences between regular Threads and virtual Threads

Skip to end of metadata Go to start of metadata

The following is a list of the subtle differences between the two types of thread:

1. VirtualThread always report their priority as NORM_PRIORITY. The priority is not inherited and cannot be changed with the setPriority method.
2. Virtual threads are daemon threads. Their daemon status cannot be changed with the setDaemon method.
3. Virtual threads cannot be suspended, resumed or stopped with the Thread suspend, resume and stop APIs.
4. Virtual threads have no permissions when running with a security manager.
5. Virtual threads are not active threads in a thread group. All virtual threads are in the same ThreadGroup. The ThreadGroup enumerate methods do not enumerate the virtual threads in the group.
