Deadlock in oscache 2.0

I'm seeing deadlocks in my application with multiple threads getting suck
with the following stack trace:

"Thread-60" daemon prio=1 tid=0x08ca7af0 nid=0x5290 in Object.wait()
[b71ff000..b71ffb6c]
  at java.lang.Object.wait(Native Method)

at com.opensymphony.oscache.base.Cache.getFromCache(Cache.java:183) at
com.opensymphony.oscache.general.GeneralCacheAdministrator.getFromCache(GeneralCacheAdministrator.java:128)

Here's my oscache.properties:

cache.useHostDomainInKey=true
# Not needed but was left in when I used to use a cache.persistence.class
cache.path=/usr/local/web/jakarta-tomcat/oscache
cache.algorithm=com.opensymphony.oscache.base.algorithm.LRUCache
cache.capacity=500

Is this a known issue?  It seemed to be worse when I a
cache.persistence.class was specified. (DiskPersistenceListener)

I never had this issue with oscache 1.7.5 before upgrading to 2.0.
