> There are some edge cases that invalidate the flattened indexes, that are not accounted for.  One is what happens when a pipeline transitions from non-JCas to JCas generators.  Any flattened index built before this transition will have the incompatible kinds of Java Cover classes. 
> The other happens within a PEAR context - during that part of a pipeline, the classpath is altered, and the PEAR could be redefining the Java cover classes.  
> There may be others.  For now, because measurements in real-life situations didn't show much if any improvement, the fix is to disable this feature.
