Grails/Ehcache Tip

Another one to remember.

Ehcache (used by default in the later releases of Grails) has an update checker that apparently is on by default.

Innocuous but a bit of a pain: consider the potential adverse affects for a production box.

If that doesn’t make you nervous…consider trying to investigate this [putatively unexplained] behaviour during a load testing session conducted in front of your [also putatively, nervous] manager (been there, wasn’t pretty: “What’s this spike? What’s this spike? What’s this spike.”)…

If that wasn’t enough to get you sweating, well: according to Sven Lange in A web geek’s blog:

UpdateChecker is not only looking for updates. In addition it also submits information about the applications environment to Terracotta by default. And this sucks in my opinion.

It sucks in my opinion, too. This is why I want to keep this link hanging around.
