likely it is.

WORK AROUND Clearing disk cache to force full download. This is not a solution for a bandwidth considered environment, because it forces download of complete jar files. ###@###.### 2004-11-11 17:01:54 GMT

SUGGESTED FIX Modify DiskCache.getTempCacheFile to create unique filenames. ###@###.### 2004-11-11 17:01:54 GMT see: http://web-east.east/www/webrevs/andy/1.6.0/6194024/ ###@###.### 2004-11-11 17:32:53 GMT
