[wtp-releng] When it rains it pours ... ICU version change

[David M Williams <david_williams@xxxxxxxxxx>]

The very very latest platform updated
their ICU4J bundle to "4.2" and wouldn't you know it ... we still
have 6 that specify an upper bound: 

org.eclipse.jem.util
org.eclipse.jst.j2ee
org.eclipse.jst.j2ee.core
org.eclipse.jst.j2ee.ui
org.eclipse.jst.j2ee.web
org.eclipse.wst.web

I will attempt to change these so they
just have their existing lower bound. That's their recommendation for this
case ... to only have a lower bound. 

At the first sign of trouble, such as
if I go to release, and there is more in HEAD than just this version change,
I'll back off and go back to yesterday's Platform. 

Sorry for the churn,
