Fwd: Commons JCS - disk cache bugs

Hi,

I'm trying to integrate Commons JCS into Java OpenStreetMap editor
(http://josm.openstreetmap.de). During tests I see, that from time to
time IndexedDiskCache is thrown away. I've made a simple unit test
that detects this situation:
https://issues.apache.org/jira/browse/JCS-146

Also, I took some time to find the bug, and I attached small patch
that fixes this issue.

I tried also to use BlockDiskCache, that doesn't need optimization at
all, but there is some locking problem:
https://issues.apache.org/jira/browse/JCS-144

For which I've also attached the patch.

I see that JCS project doesn't enjoy much activity, but is there any
chance, that someone could review and commit JCS-144 and JCS-146?

I'd really enjoy, if I could have a fix in mainstream repository
instead of keeping local patches within JOSM tree.

Cheers,

Wiktor

I already had a look at the patches. I'll try to include them soon.

Bye, Thomas.
