org.apache.http.impl.client.cache.memcached.MemcachedHttpCacheStorage
Original (in getEntry function):
byte[] data = (byte[]) client.get(url);
Should be:
Object obj= client.get(url);
if (null == obj || !(objinstanceof byte[])) {
return null;
}
byte[] data = (byte[])obj;
Original (in updateEntry function):
byte[] oldBytes = (v != null) ? (byte[]) v.getValue() : null;
Should be:
byte[] oldBytes = (v != null && (v.getValue() instanceof byte[])) ? (byte[])
v.getValue() : null;
