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.
