Exception thrown when parsing GenBank file

Hi all, 

I am currently trying to debug a little software application which uses BioJava's core-1.8.1.jar library because it has started to throw exceptions a while ago.  

I guess the problem is, that the GenbankLocationParser is not able to handle "Het" entries in the features section of the GenBank/GenPept format, e.g.  

 Het             join(bond(9),bond(125))  
                     /heterogen="( NA,   5 )"  

for database id 14719485 (http://www.ncbi.nlm.nih.gov/protein/14719485) .  

Calling   

new GenpeptRichSequenceDB().getRichSequence("14719485");  

will result in an error message like:  

Error while querying 14719485!

I have checked several other database entires and none of the ones that worked had a "Het" entry. But I also failed at 56965892, 13786715, 209156668 and 12084365. Has anybody else come across this problem or knows how to fix it?  

Thanks,  
 Dietmar
