Re: [JCS] disk persistence - same conf file, different results

[Duncan Jones <dj...@apache.org>]

Hi João,

This is probably best addressed to the Commons user mailing list. I've
BCC'd the issues list so people know where this email thread went to.
Please also prefix the Commons component into the subject line (in
this case [JCS], which I've done for you).
