Spring ACL issue with disk store ehcache - spring

Question

I'm trying to implement Spring ACL, but I encountered an issue to which i have no clue of how to solve.
We have a running configuration of echache which is loaded from the following spring context.

I tried removing the <diskStore path="java.io.tmpdir"/> line in the ehcache, but to no avail.
EDIT
Spring version: 3.2.4.RELEASE
Ehcache version: 4.1.9.Final

Answer 1

According to EhCache documentation, you can turn off usage of disk for a cache by setting the overflowToDisk attribute to false. So you could try :
<defaultCache
maxElementsInMemory="10000"
overflowToDisk="false"
eternal="false"
timeToIdleSeconds="120"
timeToLiveSeconds="120"
diskExpiryThreadIntervalSeconds="120"
statistics="true"
memoryStoreEvictionPolicy="LRU"/>
