Unhandled event loop exception [message #1052919] Wed, 01 May 2013 11:57

Installed www. eclipse. org/downloads/download.php?file=/technology/epp/downloads/release/kepler/M6/
on Windows 7 Ultimate w/ Service Pack 1. Java is...
c:\>java -version
java version "1.7.0_03"
Java(TM) SE Runtime Environment (build 1.7.0_03-b05)
Java HotSpot(TM) Client VM (build 22.1-b02, mixed mode)

Eclipse Kepler comes up with `Welcome to Eclipse for RCP and RAP Developers' fine.
Then loaded plugins from download. vogella. com/kepler/e4tools
checked the Eclipse e4 Tools. Fine.
When I then did File -> New -> Other... -> Eclipse 4 -> Eclipse 4 Application Proj
Gave it a name, checked the `Create sample content (parts, menu etc)' and
pressed the Finish button, got three errors...
all Unhandled event loop exceptions on plug-in org.eclipse.ui

I also tried the plugin from download. eclipse. org/e4/updates/0.13/ and
download. eclipse. org/e4/updates/0.12/ with different items selected such
as both E4 CSS Spy and Eclipse e4 Tools. I also tried including other plugins.
Also tried to use e4 Juno instead of Kepler. Permutted plugins etc.
Always the same. Before I re-install, I delete the eclipse install directory and
the workspace directory to mitigate version pollution, although I did not re-boot.
Tried working with Lars Vogel via email (he was helpful) but did not resolve.
Any help would be appreciated, am running out of headache meds.
These errors are very repeatable and beginning to annoy. Here is one of the
error traces...
