Donald Woods commented on GERONIMO-5553:
----------------------------------------
In geronimo-transformer, the TransformerWrapper class is commented out and no
longer used, but geronimo-persistence-jpa20 and geronimo-aries-jpa contains its
own implementation of TransformerWrapper, which only calls the transformer if
the provided classloader is an instance of BundleReference? Is that the right
behavior for geronimo-persistence-jpa20 for a WAR case, where it is not a
Bundle? Seems okay for the Aries case...
public byte[] transform(ClassLoader loader, String className, Class<?>
classBeingRedefined, ProtectionDomain protectionDomain, byte[] classfileBuffer)
throws IllegalClassFormatException {
if (loader instanceof BundleReference && ((BundleReference)
loader).getBundle() == bundle) {
try {
return classTransformer.transform(loader, className,
classBeingRedefined, protectionDomain, classfileBuffer);
} catch (IllegalClassFormatException e) {
throw e;
} catch (RuntimeException e) {
return null;
}
}
return null;
