    Typically the JVM allows each thread the opportunity of being executed on its own core.

    Typically more so for unix environments and not as well for windows based operating systems.

    I think you could do with qualifying that last statement.

    There are definitely differences in the thread scheduling algorithms of Windows vs Linux/other Unices (for example, look at how thread priority behaves on Windows vs Linux), and depending on the circumstances one or other scheduler algorithm could be considered "better". But on both types of platform, a Java thread generally maps to an OS thread nowadays.
