Resolution: Won't Fix
Affects Version/s: 3.3
Fix Version/s: None
after upgrading to lucene 3.1+, I see this in my log:
java.lang.AssertionError: TokenStream implementation classes or at least their incrementToken() implementation must be final
Turns out I derived TokenStream and my class was not declared final.
This silently breaks backward compatibility via reflection, scary...
I think doing this sort of check is fine, but throwing an java.lang.AssertionError in this case is too stringent.
This is a style check against lucene clients, a error log would be fine, but throwing an Error is too much.
