java - 从 Java 1.6 切换到 Java 1.7 后出现 memcached 错误

Question

MemcacheD 一直运行良好，直到我们最近从 Java 6 切换到 Java 7。现在我们不断收到如下异常：

java.lang.RuntimeException: Exception waiting for value
    at net.spy.memcached.MemcachedClient.get(MemcachedClient.java:1025)
    at net.spy.memcached.MemcachedClient.get(MemcachedClient.java:1042)
...
...
Caused by: java.util.concurrent.ExecutionException: java.lang.RuntimeException: Cancelled
    at net.spy.memcached.internal.OperationFuture.get(OperationFuture.java:169)
    at net.spy.memcached.internal.GetFuture.get(GetFuture.java:62)
    at net.spy.memcached.MemcachedClient.get(MemcachedClient.java:1021)

和这个

java.lang.RuntimeException: Failed waiting for store
    at net.spy.memcached.MemcachedClient.mutateWithDefault(MemcachedClient.java:1696)
    at net.spy.memcached.MemcachedClient.incr(MemcachedClient.java:1806)
...
...
