i was looking at the diffs here because i was going to propagate this
change to jakarta-tomcat-connectors, but i'm no sure i understand this:

perhaps i'm missing something, but it looks like the offset returned by
getOffset() should be the offset into the byte array contained in
ByteChunk, which would be the start position in this case, rather than
the end position.
also, if you look at the append() and equals() methods that take
ByteChunk's as arguments, if getOffset() returns the end position rather
than the start position, these methods won't work as intended. for
example, equals() will start comparing comparing bytes at the end of the
ByteChunk, rather than the start of it.
just a sanity check...
