    A UNO interface seems to be at the wrong abstraction level for this
    functionality (also, the C++ classes <code>jvmaccess::VirtualMachine</code>
    and <code>jvmaccess::UnoVirtualMachine</code> used by
    <member scope="com::sun::star::java">XJavaVM::getJavaVM</member> are not
    part of the public C++ UNO runtime API).  This should probably be replaced
    by an appropriate C/C++ API.

	/** returns the address of the Java Virtual Machine. 

		<p>If the VM is not already instantiated, it will be now.</p>

        <p>If the <code>processID</code> is a normal 16-byte ID, the returned
        <atom>any</atom> contains a JNI <code>JavaVM</code> pointer as a
        <atom>long</atom> or <atom>hyper</atom> integer (depending on the
        platform).  If the <code>processID</code> does not match the current
        process, or if the VM cannot be instantiated for whatever reason, a
        <void/> <atom>any</atom> is returned.</p>

        <p>If the <code>processID</code> has an additional 17th byte of
        value&nbsp;<code>0</code>, the returned <atom>any</atom> contains a
        non&ndash;reference-counted pointer to a (reference-counted) instance of
        the C++ <code>jvmaccess::VirtualMachine</code> class, always represented
        as a <atom>hyper</atom> integer.  The pointer is guaranteed to be valid
        as long as the reference to this
        <type scope="com::sun::star::java">XJavaVM</type> is valid (but the
        pointer should be converted into a reference-counted reference as soon
        as possible).  Again, if the first 16 bytes of the
        <code>processID</code> do not match the current process, or if the VM
        cannot be instantiated for whatever reason, a <void/> <atom>any</atom>
        is returned.</p>

        <p>If the <code>processID</code> has an additional 17th byte of
        value&nbsp;<code>1</code>, the returned <atom>any</atom> contains a
        non&ndash;reference-counted pointer to a (reference-counted) instance of
        the C++ <code>jvmaccess::UnoVirtualMachine</code> class, always
        represented as a <atom>hyper</atom> integer.  The pointer is guaranteed
        to be valid as long as the reference to this
        <type scope="com::sun::star::java">XJavaVM</type> is valid.  Again, if
        the first 16 bytes of the <code>processID</code> do not match the
        current process, or if the VM cannot be instantiated for whatever
        reason, a <void/> <atom>any</atom> is returned.</p>

        <p>The first form (returning a JNI <code>JavaVM</code> pointer) is
        mainly for backwards compatibility, new code should use the second form
        (returning a pointer to a <code>jvmaccess::VirtualMachine</code>) if it
        does not want to use the Java UNO environment, and it should use the
        third form (returning a pointer to a
        <code>jvmaccess::UnoVirtualMachine</code>) if it wants to use the Java
        UNO environment.  For example, one advantage of using
        <code>jvmaccess::VirtualMachine</code> instead of the raw
        <code>JavaVM</code> pointer is that whenever you attach a native thread
        to the Java virtual machine, that thread's context
        <code>ClassLoader</code> (see
        <code>java.lang.Thread.getContextClassLoader</code>) will automatically
        be set to a meaningful value.</p>

        @param processID
        The process ID of the caller's process, possibly extended by a 17th byte
        of value <code>0</code> or&nbsp;<code>1</code>.

        @return
        On success, the <atom>any</atom> contains a pointer represented as
        <atom>long</atom> or <atom>hyper</atom>, otherwise the <atom>any</atom>
        is <void/>.
