I have willow moss that puts on these type of skinny growth.  It has grown 
tall enough to be above water.  I think it's a light level thing.  If it's 
getting enough light, it probably think it's close enough to water surface, 
so it put out these vertical growth to get to the top.  These vertical 
growth quite resemble the above water look of moss.  Mine grows in a 
unheated tank where the room temperature is around 22 degree C.  I don't 
think it's temperature or nutrient deficiency.  But what do I 
know??  =)  Although I have never seen my java moss stretch and put on 
vertical growth, only the willow moss.
