Claire McGinty updated BEAM-10604:
----------------------------------
    Description: 
https://github.com/apache/beam/blob/6fdde4f4eab72b49b10a8bb1cb3be263c5c416b5/sdks/java/core/src/main/java/org/apache/beam/sdk/io/FileBasedSource.java#L215

Can we remove the "final" modifier here so subclasses have the option to 
override? I have a subclass implementation that performs best with a different 
size estimation heuristic. Similar case with the #split method..
