[jira] [Created] (ARIES-808) Problem with JPAWeavingHook in an
environment that uses Composite Bundles
Problem with JPAWeavingHook in an environment that uses Composite Bundles
-------------------------------------------------------------------------
Key: ARIES-808
URL: https://issues.apache.org/jira/browse/ARIES-808
Project: Aries
Issue Type: Bug
Components: JPA
Environment: I am using Equinox org.eclipse.osgi_3.7.2.R37x_v20111028-1418.jar with Apache Aries revision 1187719
Reporter: Brian DePradine
Priority: Critical
When running my OSGi application that uses JPA I get the following error:

I am using Apache Aries with Composite Bundles in order to run my application. Due to the fact that we are using OSGi 4.3 we are using the JPAWeavingHook to perform load time enhancement of our entities. The JPAWeavingHook makes use of the org.apache.aries.jpa.container.weaving.impl.WrappingTransformer to help it determine which packages need to be added as dynamic imports. It contains the following code:
public WrappingTransformer(ClassTransformer delegate,
ServiceReference<?> persistenceProvider) {
if(delegate == null)
throw new NullPointerException(NLS.MESSAGES.getMessage("jpa.weaving.null.transformer"));
if(persistenceProvider == null) {
throw new NullPointerException(NLS.MESSAGES.getMessage("jpa.weaving.null.provider"));
}
this.delegate = delegate;
Object packages = persistenceProvider.getProperty("org.apache.aries.jpa.container.weaving.packages");
Bundle provider = persistenceProvider.getBundle();
String suffix = ";" + Constants.BUNDLE_SYMBOLICNAME_ATTRIBUTE + "=" +
provider.getSymbolicName() + ";" + Constants.BUNDLE_VERSION_ATTRIBUTE
+ "=" + provider.getVersion();
if(packages instanceof String[]) {
for(String s : (String[]) packages) {
if (s.contains(Constants.BUNDLE_SYMBOLICNAME_ATTRIBUTE)) packageImportsToAdd.add(s);
else packageImportsToAdd.add(s + suffix);
}
} else {
BundleRevision br = provider.adapt(BundleWiring.class).getRevision();
for(BundleCapability bc : br.getDeclaredCapabilities(BundleRevision.PACKAGE_NAMESPACE)) {
packageImportsToAdd.add(bc.getAttributes().get(BundleRevision.PACKAGE_NAMESPACE) + suffix);
}
}
}
The problem is that the suffix is meant to tie the dynamic imports to the persistence provider bundle so that they only work if the packages come from that bundle. When using Composite Bundles, however, the bundle that provides those packages will be the surrogate bundle and not the original persistence provider bundle. This results in the ClassNotFoundException listed above. As a workaround I can remove the suffix so that the imports can be used from any bundle, but I am not sure what the long term fix should be that would allow the JPAWeavingHook to work both with and without Composite Bundles.

[jira] [Commented] (ARIES-808) Problem with JPAWeavingHook in an
environment that uses Composite Bundles

Brian DePradine commented on ARIES-808:
---------------------------------------
Hi Tim,
Thanks for the response. I did consider your suggested solution, but the problem that I have is that the packages are exported by the surrogate bundle in the composite framework. Unfortunately, I don't know the bundle symbolic name of the surrogate bundle at the time that the packages are added as a property of the persistence provider service, as it is generated based on the application that is installed.

[jira] [Commented] (ARIES-808) Problem with JPAWeavingHook in an
environment that uses Composite Bundles
Posted by "Timothy Ward (Commented) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/ARIES-808?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13188766#comment-13188766 ]
Timothy Ward commented on ARIES-808:
------------------------------------
If I interpret your last comment correctly, would adding the weaving packages property to your service (without a bundle symbolic name attribute) and changing:
if(packages instanceof String[]) {
for(String s : (String[]) packages) {
if (s.contains(Constants.BUNDLE_SYMBOLICNAME_ATTRIBUTE)) packageImportsToAdd.add(s);
else packageImportsToAdd.add(s + suffix);
}
to :
if(packages instanceof String[]) {
for(String s : (String[]) packages) {
packageImportsToAdd.add(s);
}
work for you?
It's much less invasive to the code, doesn't add any special knowledge of composites, and as there hasn't been a release of the JPA weaving function it can't break any existing releases. As you can use the Composite to control which imports are available through the Surrogate it gives exactly the same level of control. What do you think?

[jira] [Commented] (ARIES-808) Problem with JPAWeavingHook in an
environment that uses Composite Bundles
Posted by "Timothy Ward (Commented) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/ARIES-808?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13186821#comment-13186821 ]
Timothy Ward commented on ARIES-808:
------------------------------------
Hi Brian,
Having reviewed the patch I have significant reservations about adding it to the codebase. Composites are a deprecated feature of Eclipse, that are entirely replaced by Resolver Hooks. I would not want to add more complex code to special case the structure of your environment.
There is also a much simpler fix for your issue - you highighted the following code:
if(packages instanceof String[]) {
for(String s : (String[]) packages) {
if (s.contains(Constants.BUNDLE_SYMBOLICNAME_ATTRIBUTE)) packageImportsToAdd.add(s);
else packageImportsToAdd.add(s + suffix);
}
}
Looking closely, wouldn't the simplest fix for you be to add the weaving packages property (complete with bundle-symbolicname attributes) to your Persistence Provider service? This would not need any change to the JPA container, and is how it was intended to be used.
Tim

---------------------------------------
Hi Tim,
That change would work for me. My proposed fix was an attempt to avoid the suffix so removing it entirely would be good.

Due to the fact that we are using OSGi 4.3 we are using the JPAWeavingHook to perform load time enhancement of our entities.

> The problem is that the suffix is meant to tie the dynamic imports to the persistence provider bundle so that they only work if the packages come from that bundle. When using Composite Bundles, however, the bundle that provides those packages will be the surrogate bundle and not the original persistence provider bundle. This results in the ClassNotFoundException listed above. As a workaround I can remove the suffix so that the imports can be used from any bundle, but I am not sure what the long term fix should be that would allow the JPAWeavingHook to work both with and without Composite Bundles.
