I have a problem with package explorer view after updating to eclipse 2.1.0.
I alway get the message "An error has occurred when creating this view" in

In my case there are no CustomFiltersActionGroup preferences
in pref_store.ini. I tried scrubbing pref_store.ini clean,
but that did not help. The crash first appeared this
morning. I had been using 2.1 and the package explorer for
a few weeks without incident. The other puzzle is that the
supposedly missing class,
CustomFiltersActionGroup$ShowFilterDialogAction, is present
in the 2.1 jdt.jar but not in the 2.0 version. Is there
some way that my 2.0 plugins are visible to the
cloassloader?

Is there any good summary info on these incompatibilities
and on upgrade considerations?
I installed 2.1 in parallel with 2.0 since I wanted to do
some testing to ensure it would work Ok on my projects with
our plugins. 2.0 was in c:\eclipse and 2.1 was in
c:\eclipse2.1. I was surprised and alarmed when 2.1
silently found all my projects in c:\eclipse\workspace and
started working on them. I wanted to and expected to have
to manually import old projects as you recommend.
I was more alarmed when I found out that I could no longer
run 2.0! WTF??? I was trying to act cautiously, but
Eclipse was too smart for that and just plunged me head
first into 2.1 -- no going back.
Now I'm learning that there are compatibility and upgrade
issues between 2.0 and 2.1? Please tell me more.
Cheer,
KC Jones
I'm running 2.1 on Win2K. .metadata/.log looks like:

That's pretty glib. Also not helpful.
Turns out my crash was a classpath issue. I also tend to
think it is a bug, but its debatable I suppose.
What happened was I installed 2.1 in parallel with 2.0, as
noted earlier. But I launched 2.1 using a 2.0 desktop
shortcut that I modified to point to the 2.1 eclipse.exe.
The shortcut specified the 2.0 directory as the working
directory. By starting 2.1 (c:\eclipse2.1\eclipse.exe) in
the 2.0 directory (c:\eclipse), 2.1 silently "found" and
upgraded all my 2.0 workspaces. Note that the shortcut does
not set any command line arguments, so there was no -data
option specified.
The confused 2.1 also appears to have found both the 2.0 and
2.1 plugins and was confused about which to use, hence the
NoClassDefFoundError crash.
The readme does not discuss where to launch eclipse.exe, nor
any impact of setting the working directory.
I'm still confused as to why 2.1 was working OK for a few
weeks before developing this Package Explorer ailment.
Presumably there was some workspace state that arose from my
edits that triggered a 2.1 feature?
In a perfect world I would expect eclipse.exe to validate
its working directory if it in fact uses that directory for
some reason. It could read the install.ini or
eclipseproduct files found there and kvetch when it finds
itself running in a older version's working directory.
I'll file the bug report if anyone else agrees that there is
a bug here. Otherwise I'm back to work...
Cheers,
KC
