Hello,

I installed a bundle programmatically using BundleContext.installBundle method. I put something like that for the bundle name (second parameter):

file://[...]/[bundleName]-[bundleVersion].jar

When I try then to update this bundle, it seems not to be correctly updated and I have a NoClassDefFoundError exception:

java.lang.NoClassDefFoundError: org/test/app/model/Test
at java.lang.Class.getDeclaredMethods0(Native Method)
at java.lang.Class.privateGetDeclaredMethods(Class.java:2444)
at java.lang.Class.getDeclaredMethods(Class.java:1808)
[...]
Caused by: java.lang.ClassNotFoundException: org.test.app.model.Test
at org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal(BundleLoader.java:513)
at org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:429)

at org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.loadClass(DefaultClassLoader.java:107)
at java.lang.ClassLoader.loadClass(ClassLoader.java:266)
... 51 more

I put a trace in the getZipFile method of the SecureAction and Equinox tries to load the following file. It correspond to the updated bundle.

[...]/workspaces/.metadata/.plugins/org.eclipse.pde.core/New_configuration/org.eclipse.osgi/bundles/155/13/bundlefile

For information, if I stop and start Equinox, things work fine!

Are there some specific things to do in order to handle bundle updates?
Thanks,
Thierry

What you describe sounds like a bug of some sorts. How are you updating specifically? Are you calling Bundle.update(InputStream) with an input stream to the new content or just calling Bundle.update() with no arguments?

It may be best for you to open a bug with specific steps to reproduce.

Hello Tom,

Thanks very much for your answer!

I use the update method with an input stream as parameter... I'll open a bug for that problem.
