problem with export of bundles when resuming an osgi application [message #77350]

hi all!

We are developing a server application using eclipse equinox 3.2. when =

resuming a framework state we recently had a problem starting one of the=
=

already installed bundles that used to work fine. the following exceptio=
n =

occurred:

org.osgi.framework.BundleException: The activator =

at =

org.eclipse.osgi.framework.internal.core.BundleLoader.create ExportPackag=
eSource(BundleLoader.java:210)

(full stack trace and log output see below)

Obviously exporter.getExporter() returns null.

>> final PackageSource createExportPackageSource(ExportPackageDescriptio=
n =

>> export) {
>> BundleLoaderProxy exportProxy =3DgetLoaderProxy(export.getExporter(=
));

My only cure was to launch the framework clean and thus delete all store=
d =

data, which is conceivably undesired.

My question is: does anybody of you know under which circumstances this =
=

error might occur and how i might prevent it?

Thanks,

Werner

This looks very similar to the bug
https://bugs.eclipse.org/bugs/show_bug.cgi?id=121148

But that bug should be fixed in 3.2. What build of Eclipse 3.2 are you
using? Try adding osgi.noLazyStateLoading=true to your config.ini.

Thanks Tom for your reply. As we were not able to reproduce the bug we d=
id =

not inquire that matter more deeply.
As it happens we were confronted with this issue today again.

We are using the release build of eclipse 3.2. the propsed fix is in the=
=

source code (we are building the osgi bundles ourself) but despite that =
it =

still seems to happen.

Is there a testsetup that i can use to reproduce this bug? this might he=
lp =

a lot in narrowing the scope of our search and help me choos a starting =
=

point.

thanks,

werner
