data passed via primitive array (e.g. byte[]) is only valid for the duration of the call. If you want something permanently shared between Java and native, you'll need to use Memory or a direct NIO buffer, and periodically synch changes.

you should definitely not hold a reference to the byte[]-originated memory, whether the object is long-lifed or not, because it's only a temporary view onto the array.

Currently with 3.0.9, at least, sometimes when I pass (long lifed) byte[] through...after say 5 minutes I pass them through, they're good in java land, but corrupted in C land. Any thoughts? -=r
