> AsyncWriter of FSHLog might throw ArrayIndexOutOfBoundsException because of
> the following code in AsyncWriter#run():
> {code}
> }
> }
> if (!hasIdleSyncer) {
> int idx = (int)this.lastWrittenTxid % asyncSyncers.length;
> asyncSyncers[idx].setWrittenTxid(this.lastWrittenTxid);
> }
> }
> {code}
> In obove code, "this.lastWrittenTxid % asyncSyncers.length" might become
> negative when this.lastWrittenTxid is bigger than Interger.MAX_VALUE where
> this.lastWrittenTxid is a long. The attachment gives a quick fix.
