我在WebSphere 8上使用RMI复制的Ehcache 2.6.3。
应用程序开始从ehcache获取此错误消息。
（PayloadUtil.java:203）无法解压缩。心跳不起作用。不是GZIP格式
可能是什么原因？
这是配置：
<cacheManagerEventListenerFactory class="" properties=""/>
<cacheManagerPeerProviderFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
properties="peerDiscovery=automatic,
multicastGroupAddress=239.21.131.242,
multicastGroupPort=${multicastGroupPort}, timeToLive=32"
propertySeparator="," />
<cacheManagerPeerListenerFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory" />
<cache name="REFERENCE_DATA"
maxElementsInMemory="1000"
eternal="false"
overflowToDisk="false"
memoryStoreEvictionPolicy="LFU"

timeToLiveSeconds="10800"

</cache>
