It is difficult to guess if this is a Jadx problem or a problem of the used smali debugging library.

In both cases without a lot more details on how details (e.g. the APK you were debugging) and what classes you were looking at when the error occurred and so on. @magicjva Can you please provide those details?

I encountered the same issue and was able to debug the APK after applying HQKTech/jdwp#2.

I made a fork for jdwp library, apply @george-hopkins fix and switch jadx to my fork, so this issue should be fixed now.
Can anyone check latest unstable build? 🙂

[george-hopkins]

Thank you for fixing the issue! I was able to debug the affected APK with jadx-1.4.4.86-29b64300.

@george-hopkins great! Thank you for patch and fix confirmation 👍
