Thread.stop()

[Mo DeJong]

I was under the impression that methods like Thread.stop() were
removed from the JDK or replaced with no-ops. I seem to remember
that they were never implemented in Netscape's JVM. The whole
concept of stoping a thread seems like a bad idea, a thread
should expire due to natural causes.

Here are some notes about it from the Sun developer site.
