Imglib plugins no longer available via ImageJ Server

Hi all,

A couple of days ago, the ImageJ Server has been improved by @ctrueden and become an ImageJ extension with great plugins allowing the user to start or to stop the server, for example.

However, some modules are no longer available via ImageJ Server. For example, I used to rotate images via the `net.imagej.plugins.commands.imglib.RotateImageXY` plugin, but it looks like that no `imglib` plugins are found by the respective service anymore.

Is this a bug or rather a logical consequence of other things? Can anyone see this plugin listed in his/her environment?

Many thanks for your help.

Best regards,
Petr

Start by reproducing the missing-plugin behavior in ImageJ Server and check whether net.imagej.plugins.commands.imglib.RotateImageXY is discoverable through the server's plugin service. Compare the current extension behavior with the older server behavior; done means determining whether the absence is a regression or expected consequence and documenting or restoring the expected availability.
