[Mondrian] question regarding CacheControl

[Ati Rosselet]

Hi,
I'm trying to get the cache to clear (using cache control), but I keep
getting errors like this:

2012-06-19 11:22:48,512 ERROR [STDERR]
java.lang.ArrayIndexOutOfBoundsException: 2112

mondrian.rolap.RolapAggregationManager$1.flush(RolapAggregationManager.java:651)

What could be causing this?  If I restart the server (jboss), then for
a while it seems to work fine.. then after the database has been
refreshed, it often, but not always starts to give me this error
I am using mondrian 3.3 branch (will move to 3.4 when I get the time :)).
Thanks
Ati
