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.
