Steps to reproduce:

1. Set up two bundles.
2. In both bundles:
Add the following properties to the portal-ext.properties:

cluster.link.enabled=true
ehcache.cluster.link.replication.enabled=true

Add "replicatePutsViaCopy=true" under "defaultCache" section in liferay-multi-vm-clustered.xml (turn others to true also).

<defaultCache
eternal="false"
maxElementsInMemory="10000"
overflowToDisk="false"
timeToIdleSeconds="600"
>
<cacheEventListenerFactory
class="com.liferay.portal.cache.ehcache.LiferayCacheEventListenerFactory"
properties="replicatePutsViaCopy=true,replicatePuts=true,replicateUpdatesViaCopy=true"
propertySeparator=","
/>
<bootstrapCacheLoaderFactory class="com.liferay.portal.cache.ehcache.LiferayBootstrapCacheLoaderFactory" />
</defaultCache>

3. Deploy ehcache-cluster-web plugins in both bundles.
4. Start up bundles in sequence.
5. On one bundle site, go to control panel -> server administration -> script.
Choose language as Groovy, put script as:

   com.liferay.portal.kernel.cache.PortalCache pc = com.liferay.portal.kernel.cache.MultiVMPoolUtil.getCache("testCacheId");
   pc.put("one", "ONE");
   pc.put("two", "TWO");
   pc.put("three", "THREE");

then hit "Execute" button.

Error Message:

No error will be seen in the whole process.

Actual result:
The Error Message was thrown in console.
