Hi Taras,

Thanks for your help. I tried the -backport option on the previously retrotranslated classes and received some errors that were resolved by including backport-util-concurrent-3.1.jar. After that I was getting some errors related to getAnnotation 1 so I tried building all the projects from scratch and running retrotranslator again together with the -backport option. Now I'm getting UnsupportedOperationException errors 2. Any advice you can give me will be greatly appreciated.

Hi Oscar,

It looks like Retrotranslator haven't translated the ConversationProcessor class if you see the following stack trace:

java.lang.UnsupportedOperationException: native method not implemented
  at java.lang.Class.getDeclaredAnnotations(Native Method)
  at java.lang.Class.getAnnotations(Class.java:204)
  at java.lang.Class.getAnnotation(Class.java:187)
  at org.apache.tuscany.sca.implementation.java.introspect.impl.ConversationProcessor.visitClass(ConversationProcessor.java:49)

Check the size of the translated class, it should become one third bigger.

If you need backport-util-concurrent-3.1.jar you have probably run Retrotranslator without specifying "-target 1.5". Always use "-target 1.5" and "-classpath retrotranslator-android-1.2.6.jar" even if repeatedly translating classes. However I recommend to translate code in one pass.

Cheers,

Taras

Hi Taras,

I think you're right, but I find weird since I have retrotranslated all classes using the backport and target options. This is how I'm running retrotranslator now:

$ java -jar ../Retrotranslator-1.2.6-bin/retrotranslator-transformer-1.2.6.jar -srcdir srcdir -backport java.rmi.Remote:java.lang.Cloneable -target 1.5 -reflection safe -stripannot -embed . -classpath ../Retrotranslator-1.2.6-bin/retrotranslator-android-1.2.6.jar -verbose

Just to double check I rebuilt my workspace and ran retrotranslator again as shown above. I don't get any errors when running retrotranslator 1 2 but still get the same errors when running the calculator-android project. Also, I checked the sizes of the translated classes and found that they are not becoming much bigger 3 4. Do you think I'm missing something?

Thank you so much for all your help.
