Bug#446328: eclipse: Welcome Screen Fails to Start, Displays Error

Package: eclipse
Version: 3.2.2-4
Severity: important
Attempts to open the Welcome screen result in a pane with an
error describing an inability to load a class. The topmost error is:
java.lang.ClassNotFoundException: org.eclipse.core.runtime.Plugin
This can most easily be reproduced by starting eclipse 'clean',
that is, without any pre-existing 'workspace' or '.eclipse' directories.
Eclipse will attempt to display the Welcome screen, but fail. Other
panes *seem* to work correctly, but I'm not very experienced with
eclipse so I can't speak to that (I'm trying to learn the darned thing,
but I keep finding bugs.)
I have the Sun JVM installed, but eclipse seems to be defaulting
to gcj. Perhaps my Debian 'alternatives' are messed up? They're set up
as:
walkies:/etc# update-alternatives --display java_vm
java_vm - status is auto.
link currently points to /usr/lib/jvm/java-6-sun/jre/bin/java_vm
/usr/lib/jvm/java-6-sun/jre/bin/java_vm - priority 63
Current `best' version is /usr/lib/jvm/java-6-sun/jre/bin/java_vm.
walkies:/etc# update-alternatives --display java
java - status is auto.
link currently points to /usr/lib/jvm/java-gcj/jre/bin/java
/usr/lib/jvm/java-6-sun/jre/bin/java - priority 63
slave java.1.gz: /usr/lib/jvm/java-6-sun/jre/man/man1/java.1.gz
/usr/bin/gij-4.1 - priority 41
/usr/bin/gij-4.2 - priority 42
slave java.1.gz: /usr/share/man/man1/gij-4.2.1.gz
/usr/lib/jvm/java-gcj/jre/bin/java - priority 1042
Current `best' version is /usr/lib/jvm/java-gcj/jre/bin/java.
I've attached the text of the error, and the output of 'eclipse
-debug'.
Thank you for your attention to this matter.
