I can replicate this in Java 11, 17, 21.

When -verbose:class is part of the client's java argumens the Java client process spawned by FWD spawner (the native spawner) hangs.

By "hangs" I mean the Java client process is running, but doesn't start executing the main class. Also Java debugger can't be attached to it. The process can be listed using jps command.

When the Java client process is started directly from the shell using the same arguments the client starts OK.

I suspect this is related to standard input/output and how native spawner processes input/output.
