No.

No.

Lower level "plumbing" commands like "git apply" want to see the
cached stat information in the index refreshed before they are
called, instead of having to refresh the index themselves before
starting to work, for performance reasons.  Higher level "Porcelain"
commands like "git status" on the other hand refreshes the index
before they start to work.

What you are seeing is a combination of

 * JGit not running its equivalent of "git update-index --refresh"
   before finishing and leaving the index file for you to look at.

 * "git status" running an equivalent of "git update-index --refresh"
   internally.

 * "git apply" not running "update-index --refresh" itself and
   instead expecting somebody else to have done so in the sequence
   of commands that it is a part of.

The latter two is working perfectly as designed.

I do not know what JGit wanted to do to leave the index in that
state, so I cannot judge if that is a reasonable thing to do or JGit
needs tobe fixed.
