Unhandled exception when clicking empty autocomplete option in interpreter window

[sad-dev]

I am using a fairly recent commit of ghidra (NationalSecurityAgency/ghidra@9e83921) and the latest (b7bedaf) of Ghidrathon

Autocomplete provides no completions for me:

and clicking it gives me an NPE (although this might be a Ghidra issue) :

Cannot invoke "java.util.List.get(int)" because "this.list" is null
java.lang.NullPointerException: Cannot invoke "java.util.List.get(int)" because "this.list" is null

Are there any possible mistakes/omissions I might have made while building/installing to look out for? It appears (#5) that autocomplete isn't a thing yet. Are there any potential problems if I run the Jython side-by-side for autocomplete and disable it before running scripts?

@sad-dev thank you for reporting. You are correct that Ghidrathon does not yet support autocomplete, however, you have identified a bug that should be addressed.

You can run the Jython interpreter alongside Ghidrathon without needing to disable. Disabling Jython is simply a recommendation, not a requirement. Just note that when both are enabled Ghidrathon takes precendance over Jython when running scripts from the Ghidra script manager and in headless mode.
