EVALUATION Java Web Start was never specified to support the cache max value as anything other than a suggestion. Since tiger has no capability of running an application w/o caching it, and no facility to automatically uninstall applications to make room for newer ones, this functionality was never planed or implemented in 1.5.0. It should, however, be part of Feature 156 in Mustang. ###@###.### 2004-12-16 15:31:37 GMT
