I am not sure if you found a solution to your problem - it has been a while
since I kept up to date on this list.
One possible reason for your problem is the way they have specified their
plug-in's dependency on the Derby plug-in. When setting up a dependency
between plug-ins you can specify a minimum version, both a minimum and maximum
version or no version at all for the plug-in yours depends on. For example in
one of my plug-ins I have a dependency on the Derby plug in that looks like
this (from my plug-in's MANIFEST.MF file):
<snip>
Require-Bundle: <snip>
org.apache.derby.core,
<snip>
This means when ever I replace the derby plug-in, regardless of what version it
is, my plug-in will try to use it. Since I am writing an RCP application and
am in total control of what ships I find this convenient.
Alternatively you can specify a minimum version for a dependent plug-in, like
this:
<snip>
Require-Bundle: <snip>
org.apache.derby.core;bundle-version="10.4.1",
<snip>
Or you can specify both a minimum and maximum (in the example below, a specific
version), like this:
<snip>
Require-Bundle: <snip>
org.apache.derby.core;bundle-version="[10.4.1,10.4.1]",
<snip>
If the plug-ins that are failing to load have a bundle-version property on
their dependency to the derby plug-in that could explain what is going on.

Subject: Plug-in won't work in "Java and Report Developers" Eclipse
Hi,
I've hit a problem which is very likely to be what was discussed in this list
here:
http://old.nabble.com/Eclipse-3.5-Plugin-%28Galileo%29-works-only-partial-tt24897570.html
I have some extra information about this (most importantly a consistent way to
reproduce):
When using the "Eclipse IDE for Java and Report Developers" installation, ANY
derby core plug-in downloaded from the Apache Derby web site is NOT detected.
This edition (btw it is an official distribution from eclipse.org) is
essentially the JEE edition together with the BIRT reporting plug-ins; You can
get it from the official Eclipse downloads site:
http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/galileo/SR1/eclipse-reporting-galileo-SR1-win32.zip
Now, compared to the pure JEE edition (where everything works properly), the
BIRT edition has the reporting plug-ins and they also show some lovin for Derby
as they include a version of the core plug-in: org.apache.derby.core_10.3.1.4
plugin.
So, I was trying to replace it with a newer version by deleting what BIRT came
with and adding the core plug-in downloaded from the Apache Derby site (tried
10.3.3.0, 10.4.2.0 and 10.5.3.0). No matter what I do, the new plugin is not
detected running "eclipse -clean -debug" does not provide any relevant
information (some birt plug-ins fail to resolve due to missing the derby core,
but there is nothing about the derby core plugin itself). It appears as though
the bundle is silently ignored and then causes the installation of a couple of
other bundles that depend on it to fail.
I'm about to head to the BIRT newsgroup to discuss this (at the very least they
should stop distributing 10.3.1.4 which has known data corruption issues), but
I'm hoping to gather some more information here first (I can point them to this
thread when I bring it up there).
Can somebody knowledgeable download the file above and have a look at the
plugins\org.apache.derby.core_10.3.1.4 folder to see what they distribute (as
far as I can see, main differences are that the network libraries are missing
and the bundle is sealed).
Hopefully, one come up with a suggestion regarding why newer versions of the
derby core are not picked up. It's probably something that they do, but I just
want an educated opinion before I head over there to complain.
Thanks
