This question does not account for Java21 virtual threads.
Yo guys, are the following assumptions true? >>

1. When Java thread is created (NEW), looks like space is allotted on heap, but no stack space is allotted.
2. When Java thread is started, by default 1MB space is allotted for stack. Btw someone said there is some kind of optimization in Java11.
3. When Java thread is started, a native thread is also created using pThread API, and managed by kernel.
4. Native thread and Java thread share the 1MB stack, and native thread has no dedicated stack of its own.
