I don't really have sample code
but the principle is just that an extension wil be loaded in core classloader,
which is unique, instead in each plugin's classloader, which leads to multiple
singleton (since this isn't JVM singleton but classloader singleton)
then I suppose that just declaring your singleton component in an extension
will give you the expected singleton, without changing any line of code in
your plugin using the component
