"Can not deserialize instance of java.util.ArrayList out of START_OBJECT token\n" exception during update of Resolution field

[swar00p]

When I try to update the Resolution field (without doing a transition) for a closed defect, I'm getting an exception (Can not deserialize instance of java.util.ArrayList out of START_OBJECT token\n). I'm willing to work on this issue if somebody can just point me in the right direction. I'm pointing to the 0.6-SNAPSHOT version of the library in my pom.xml. Full exception stack trace is given below:
