Android Studio had set the file to Read-only mode as it was confused as to the state of it's own buffer, compared to the file on disk. Once I cleared this read-only state by refreshing Studio's buffer by reading the file from disk into the buffer, this exception also went away.

Hmm, what was the file that AndroidStudio set it o readonly?

Android Studio had set the file to Read-only mode as it was confused as to the state of it's own buffer, compared to the file on disk.

Is there any other process tries to change that file?

When Comrade connect to the AndroidStudio, it won't save to disk anymore to avoid this kind of situation. Instead, it will just sync the changes to AndroidStudio's buffer.

Is there any way that i can reprodcue the issue? thanks!

[ahshah]

Let me look into reproducing for you. This happened I think in the following order:

1. Open file foo.java in vim-Comrade
2. Open same file, foo.java, in regular vim
3. Make a change in foo.java using regular vim and write to disk
4. Switch to vim-comrade and attempt to make changes (cloberring the old changes) and attempt to write the buffer
5. Navigating to studio, which was alerted to the buffer change made in step 3.

I've been able to reproduce something like what I saw, but not exactly.
Essentially you need two editors open on the same file in the project. One editor is Comrade enabled, the other one is regular vanilla nvim. If non-comrade instances write to the file, and then the comrade-enabled instance writes to the same file, clobbering over each other. causes (sometimes) an IllegalStateException.

Here's another Exception I saw
