Import-Package error for already-deployed dependency [message #1626115]

Hi all,

I'm trying to deploy a package to Virgo with a dependency on org.glassfish.jersey.core.jersey-common_2.14.0, which itself depends on javax.annotation. I'm getting the following message in the log when I do so:

An Import-Package could not be resolved. Resolver error data <Import-Package: javax.annotation; version="[1.2.0,2.0.0)">. Caused by missing constraint in bundle <org.glassfish.jersey.core.jersey-common_2.14.0>
             constraint: <Import-Package: javax.annotation; version="[1.2.0,2.0.0)">

The thing is, I am already deploying javax.annotation-api prior to this bundle being loaded. Some lines above the error in the log, I see two versions of javax-annotation being loaded:

Bundle javax.annotation_1.1.0.v201108011116, BundleEvent STARTED 
Bundle javax.annotation-api_1.2.0, BundleEvent STARTED

The second bundle is a jar which I'm deploying with my package. Looking at the MANIFEST.MF for javax.annotation-api-1.2.jar, I see that it exports the exact package that is "missing" according to the error message:

Export-Package: javax.annotation;version="1.2",javax.annotation.security;version="1.2",javax.annotation.sql;version="1.2"

Has anyone encountered anything like this?

Hi,

what flavor and version of Virgo are you using? Could you provide a simple example to reproduce the issue?

Hi,

I tried with the latest successful build from our Jenkins[1] and dropped the following bundles into the pickup folder:

hk2-api-2.4.0-b11.jar
hk2-utils-2.4.0-b11.jar
javax.annotation-api-1.2.jar
javax.ws.rs-api-2.0.1.jar
jersey-common-2.14.jar
jersey-guava-2.16.jar
org.apache.servicemix.bundles.javax-inject-1_2.jar
osgi-resource-locator-1.0.1.jar

osgi> headers 133 | grep Bundle
Bundle headers:
 Bundle-Description = Java(TM) Common Annotations 1.2 API Design Specification
 Bundle-DocURL = https://glassfish.java.net
 Bundle-License = https://glassfish.dev.java.net/nonav/public/CDDL+GPL.html
 Bundle-ManifestVersion = 2
 Bundle-Name = javax.annotation API
 Bundle-SymbolicName = javax.annotation-api
 Bundle-Vendor = GlassFish Community
 Bundle-Version = 1.2

osgi> headers 150 | grep Bundle
Bundle headers:
 Bundle-Description = Jersey core common packages
 Bundle-DocURL = http://www.oracle.com/
 Bundle-License = http://glassfish.java.net/public/CDDL+GPL_1_1.html
 Bundle-ManifestVersion = 2
 Bundle-Name = jersey-core-common
 Bundle-SymbolicName = org.glassfish.jersey.core.jersey-common
 Bundle-Vendor = Oracle Corporation
 Bundle-Version = 2.14.0
 Created-By = Apache Maven Bundle Plugin

osgi> bundle 150 | grep javax.annotation
    javax.annotation; version="1.2.0"<javax.annotation-api_1.2.0 [133]>

osgi> clload javax.annotation.PostConstruct 150

Successfully loaded [javax.annotation.PostConstruct] using class loader from:
  150	org.glassfish.jersey.core.jersey-common
  		[provided by 133 javax.annotation-api]

As you can see the Jersey bundle is wired to the javax.annotation-api bundle and able to load the provided classes.

Hope this helps,
florian

I'm not sure of how to tell which flavor or Virgo I'm dealing with, but the bundles for org.eclipse.virgo.___ are all of version 3.6.3. I've also tried the same package on a Virgo with org.eclipse.virgo packages of version 3.6.2.RELEASE, and the package deploys without a problem.

As for reproducing the issue, it looks like you just loaded the same two packages that I'm having the issue with.

Could you post the whole manifest for javax-annotation-api? The one I'm using looks like this:

Manifest-Version: 1.0
Export-Package: javax.annotation;version="1.2",javax.annotation.securi
 ty;version="1.2",javax.annotation.sql;version="1.2"
Implementation-Version: 1.2
Built-By: romano
Specification-Vendor: Oracle Corporation
Tool: Bnd-0.0.255
Bundle-Name: javax.annotation API
Created-By: 1.7.0_09 (Oracle Corporation)
Bundle-Vendor: GlassFish Community
Implementation-Vendor: GlassFish Community
Implementation-Vendor-Id: org.glassfish
Bundle-Version: 1.2
Build-Jdk: 1.7.0_09
Bnd-LastModified: 1366998437922
Bundle-ManifestVersion: 2
Bundle-License: (removed due to forum policy)
Bundle-Description: Java(TM) Common Annotations 1.2 API Design Specifi
 cation
Specification-Version: 1.2
Import-Package: javax.annotation;version="1.2",javax.annotation.securi
 ty;version="1.2",javax.annotation.sql;version="1.2"
Bundle-SymbolicName: javax.annotation-api
Bundle-DocURL: (removed due to forum policy)
Extension-Name: javax.annotation
Archiver-Version: Plexus Archiver

One thing that I noticed was that the bundle is importing the same packages that it exports. Does this imply an additional dependency for javax-annotation-api?

An overview of available flavors / deliverables is available here: https://eclipse.org/virgo/deliverables/

I used the latest Virgo Server for Apache Tomcat with the unmodified bundle available from Maven Central: http://search.maven.org/#artifactdetails|javax.annotation|javax.annotation-api|1.2|jar

Should a bundle import its own exported packages?

Thanks for the link about importing exported packages. Additionally, I just tried loading the jars one by one on a fresh install of both Virgo Nano and Virgo Tomcat 3.6.3, and jersey-common loaded without errors.

Unfortunately, the Virgo I need to run this on cannot be replaced or reinstalled as it is part of a packaged product. Is there any configuration specific to the Virgo server that could be causing this, since we're not seeing the same scenario on a fresh install?
