In the Java code the prefilter is defined as a BitSet and then converted for the C layer via BitSet.toLongArray(). Unfortunately, that method trims trailing zero words while the rest of the code seems to expect a full-length buffer, so documents at the end of the filter that should be excluded can leak into the results.
