Using 7016, jvm1.6u1 and tomcat 5.0.28:
On first run of a servlet configured to copy resources to an exploded directory, all is well. If start and stop tomcat, all resources are removed from exploded directory and are never copied back, even with rebuild project. Restart idea, and resources will be copied on first run.
Reverting to 7002 with the same project works fine.
