Thanks for drawing my attention on this. In fact the issues were few 
lines before the quoted part, there were 4 calls to non existing methods 
or fields in Java classes. I guess upstream does not see this because 
they have an ad-hoc build script which probably does not compile all 
classes. So it is likely there is some vintage code here, that could be 
removed. I opened a ticket on the page of BBmap to say so and I uploaded 
the Debian package with some fixes to correct the 4 errors!
