Description

The following code is repeated 4 times and should be put in a method that either throws the Exception or returns the incremented version (see below).

version = setDataRequest.getVersion();
int currentVersion = nodeRecord.stat.getVersion();
if (version != -1 && version != currentVersion) {
    throw new KeeperException.BadVersionException(path);
}
version = currentVersion + 1;

private static int checkAndIncVersion(int currentVersion, int versionToCompare, String path )
