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.

<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>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 <code>0</code>, the returned <atom>any</atom> contains a
non–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 <code>1</code>, the returned <atom>any</atom> contains a
non–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
