[news.eclipse.webtools] Eclipse+WTP 3.4M7 startup trouble!?

[Frits Jalvingh <jal@xxxxxx>]

I just installed Eclipse 3.4m7 and wtp 3.0 m7 by untarring the eclipse gtk
tar and unzipping the WTP files over that. This usually works without any
problem.
But now, when I start this installation, I get:
- the Eclipse splash screen
- Eclipse uses CPU for some 10 seconds, then the CPU stays idle
- The splash stays on-screen for > 10 minutes(!)
- After the 10 minutes Eclipse starts, but WTP is not installed.

The console shows:

I did notice that in M6 the new update manager caused huge startup delays
also when new software was installed (about 4 minutes for the 1st startup
when new software was installed) but that continued to use CPU all that
time AND resulted in a usable installation....

Any thoughts on this?
