> DefaultTwoWayKey2StringMapper uses two neat tricks.
> 1. it does not encode all supported types, it only encodes non-Strings. Strings are kept unmodified.
> 2. it uses a special prefix (unicode char 0xfeff) to mark which strings were encoded and which are plain.
> Unfortunately some databases, notably MySql, interpret the endianness mark (0xfeff, 0xfffe), convert to native byte order and then drop it.
> This leaves us with no clue the string is not an actual String but an encoded representation of another type. This misinterpretation leads later to ClassCastExceptions in various places in core and user code.
> Proposed fix: get rid of #1 and #2 optimisations. Encode all objects, including Strings and always use the ?n prefix (where n stands for the original type). Drop the 0xFEFF marker prefix.

> A, C and E install topology T+1, B and D do not
> E requests and receives tx data from C, including tx1
> C leaves
> B sees a SuspectException, sends rollbackCommand(tx1) to C, D
> D removes tx1
> C has left, but is ignored
> B reports to the user that the tx has been rolled back
> B and D install topology T+1 (optional)
> A starts installing topology T+2: owners(k) = [D], pending_owners(k) = [E]
> A, B, D, E all install topology T+2
> E requests and receives state from D, but it does not remove tx1
> A starts installing topology T+3: owners(k) = [E], pending_owners(k) = null
> E now has a stale backup lock on k
> It seems very hard to reproduce in production: C would have to leave soon enough so that B and D haven't received the T+1 topology yet, but late enough for it to send its transaction data to E.
> A possible solution would be to catch any SuspectException during prepare/commit/rollback (without ignoring leavers), wait for a new topology, and replicate the command again on the new owners. Obviously, this wouldn't work with asynchronous prepare/commit/rollback.

[JBoss JIRA] (ISPN-4851) Make SyncConsistentHashFactory the default CH factory

> With ISPN-4682 fixed, SyncConsistentHashFactory should be good enough to be the default. It still allows for more variation in the number of owned segments per node (+/-10% owned segments and +/-20% for primary-owned segments), but that should be acceptable for most purposes.
> The major advantage of SCHF is that it depends only on the cache members and not on the order they joined. Users expect a key to map to the same node in all caches (as long as the caches have the same members).
> One downside of SCHF, especially for testing, is that the segment ownership differs between test runs (being based on the random address assigned to each node). However, most tests that depend on key ownership should use {{ControlledConsistentHashFactory}} anyway.
> We also need to verify that the number of segments moved by SCHF is comparable to the number of segments moved by DefaultConsistentHashFactory (ISPN-3729).
