This problem exists in at least one other target (see the CSharp code). Shouldn't the fix be applied across all targets? |

Resolved the issue raised in #4843. According to the convention, invokingState.transition(0) should be a RuleTransition, but I found that sometimes it can also be an EpsilonTransition. So I tried following this EpsilonTransition to find the actual RuleTransition.
The method to reproduce this issue can be found in the issue #4843
