I'm really surprised that this code does not abend or toss some kind of error,

suppose it could be related to when the JVM actually runs the garbage
collection that recovers the storage, but to my mind this is an error just
waiting to happen.
Am I right? If not can someone provide clarification as to why the original
form is correct?
It probably works because the storage still contains the original
contents after it is released, and it is only "released" back to the JVM
not freed. The window for it to be actually overwritten is short.
I think you are correct, but there may be another problem.
GetStringUTFChars probably returns a copy of the string, but that is not
guraranteed. If it is not a copy I don't think you should modify the
original array. You probably want to copy it first and then perform
__atoe on the destination.
