Obviously my memory is not what it used to me.
Your comment rings a bell.  I now recall having come
to a similar conclusion when I investigated this originally.

Perhaps we should have a hybrid of the two append mode
implementations where
opening a FileOutputStream in append mode works as
it did in JDK 6, but we provide an extra non-public
way to construct a FileOutputStream that would open
using FILE_APPEND_DATA as in current JDK7.  This secret
constructor would only be used by the process creation
code.  That would result in minimal changes to the
process code.
