Description
Is your feature request related to a problem? Please describe.
The heap dump produced by VisualVM, and the Thread tab in the UI, do not show virtual threads.
Describe the solution you'd like
The heap dump should show virtual threads and their associated stack-trace (e.g. jcmd <pid> Thread.dump_to_file <file>). The Thread UI tab should show virtual threads.

Research direction
Start by examining the heap-dump output and the Thread tab in VisualVM, then compare their current thread handling with the virtual-thread information produced by jcmd <pid> Thread.dump_to_file <file>. Done means heap dumps include virtual threads and their associated stack traces, and the Thread tab displays virtual threads.
