Comment 2 Martin Kozeny 2014-03-28 08:00:25 UTC 
You are missing manifest.mf in your module when adding layer.xml file and that's why error occurred. Closing as WONTFIX.
Comment 3 nvamelichev 2014-06-23 02:49:14 UTC 
This should not fail with a runtime exception - it should show error message that MANIFEST.MF is not found, at least. 

And generating a MANIFEST.MF isn't that hard either: you only have to have it contain
Manifest-Version: 1.0
OpenIDE-Module-Layer: <path_to_layer.xml>
Comment 4 Martin Kozeny 2014-06-23 09:30:03 UTC 
True there should be an error message, not failing with RTE. When creating new NB module, Manifest is created but here was probably manually deleted.
