New Revision: 1758882

URL: http://svn.apache.org/viewvc?rev=1758882&view=rev
Log:
the FST linking engine now checks if a FST corpus is present for a given 
Language in the compute method. This is to avoid situations where a corpus 
became unavailable in-between the canEnhance and computeEnhancement calls.
