Will do that - but just wondering what the intended behavior is; I would 
expect that facet's should be encouraged to do similar things when it 
comes to libraries....and the "Server provides libraries" option for 
these two would indicate they at least should let the runtime know about 
the changes.

In any case: Is there a way for a runtime to know which facet's are 
being added to a project that it is connected to ?

e.g. if I move a project from runtime/server A to runtime/server B the 
classpath should be updated - but that does not seem to happen. Should 
it not ?
