ehCache CacheManager warning

[shrestha]

Upgrading to Grails 1.2M4, I get this message when running Grails:

net.sf.ehcache.CacheManager detectAndFixDiskStorePathConflict
WARNING: Creating a new instance of CacheManager using the diskStorePath
"C:\Users\ROSHAN~1\AppData\Local\Temp\/_logmedoCache" which is already used
by an existing CacheManager.
The source of the configuration was classpath.
The diskStore path for this CacheManager will be set to
C:\Users\ROSHAN~1\AppData\Local\Temp\/_logmedoCache\ehcache_auto_created_1258235057657.
To avoid this warning consider using the CacheManager factory methods to
create a singleton CacheManager or specifying a separate ehcache
configuration (ehcache.xml) for each CacheManager instance.

Searching for CacheManager, I do see it being used by
AcegiGrailsPlugin.groovy

I do have "ehCache.xml" under "conf", which I am using to configure a cache
that i am using in some parts of my code. Upon deleting this file, and
disabling my caching code, the messages I get on startup are:
