[evla-sw-discuss] Power outage tomorrow

[James Robnett]

Forgot to put in that Stephan will be changing the java
version that tomcat uses out at the site use from
1.6.0_26 to 1.6.0_34.

This only effects tomcat on those servers, not other software
that uses java.

That happens before Kscott starts shutting things down at 7:30.\
