Problem Description: java.util.ConcurrentModificationException stop most of graphical data output in Server Monitoring when cached queries are stored in QUERY region supported by Ehcache (Use internal cache to store queries NOT flagged) and custom caches are used.

The error message is:
C:\ColdFusion10\cfusion\wwwroot\CFIDE\adminapi\servermonitoring.cfc
Wednesday, Apr 10, 2013  8:19:41 PM
flex.messaging.MessageException : java.util.ConcurrentModificationException

Steps to Reproduce:

1) Unflag "Use internal cache to store queries" in Coldfusion Administror to store queries in QUERY region supported by Ehcache
2) Create some custom caches in ehcache.xml like:

<cache name="query_15m"
	maxElementsInMemory="10000"
	eternal="false"
	timeToIdleSeconds="900"
	timeToLiveSeconds="900"
	overflowToDisk="false"
	diskSpoolBufferSizeMB="30"
	maxElementsOnDisk="200000"
	diskPersistent="false"
	diskExpiryThreadIntervalSeconds="900"
	memoryStoreEvictionPolicy="LRU"
	clearOnFlush="true"
	/>

	<cache name="query_01h"
	maxElementsInMemory="10000"
	eternal="false"
	timeToIdleSeconds="3600"
	timeToLiveSeconds="3600"
	overflowToDisk="false"
	diskSpoolBufferSizeMB="30"
	maxElementsOnDisk="200000"
	diskPersistent="false"
	diskExpiryThreadIntervalSeconds="3600"
	memoryStoreEvictionPolicy="LRU"
	clearOnFlush="true"
	/>

	<cache name="query_01d"
	maxElementsInMemory="10000"
	eternal="false"
	timeToIdleSeconds="86400"
	timeToLiveSeconds="86400"
	overflowToDisk="false"
	diskSpoolBufferSizeMB="30"
	maxElementsOnDisk="200000"
	diskPersistent="false"
	diskExpiryThreadIntervalSeconds="3600"
	memoryStoreEvictionPolicy="LRU"
	clearOnFlush="true"
	/>

3) Start Server Monitoring

Actual Result:
