not only that, it can be a real bug as well (though isn't in this case).
the OUString, or more precisely the buffer it holds, is immutable by
design, and has a intern() method that effectively enters it into a
global hash-table; if an intern()ed string is later modified then that
hash table is going to be very unhappy (about unhappy hashtables, see
also 3ea6b1c1594fa3fdb7e13c544b3beecd369b67d0).

right: if you want to modify an OUString, use OUStringBuffer, that's why
it exists.
