In "Proposed Final Draft 2" (coming soon) you will see that init() and
destroy() are the final answer. This change was approved by the JSR-053
expert group after the "Proposed Final Draft" version was published, and
Tomcat was changed at that time.
There will be a few more minor changes in Tomcat 4.0 (not API related) to
reflect other clarifications that will be in PFD2.
