Fewer than 70 loaded plugins breaks loading of Gemini Code Assist

[stimut]

If fewer than 70 plugins are enabled, I receive the below errors on startup and Gemini Code Assist is non-functional. I found this by essentially binary searching why the plugin works with a new config, but my streamlined one did not.

I have confirmed that it is the number of plugins enabled, and not the specific plugins, by:

• trimming the enabled plugins to 70
• try disabling, testing, and re-enabling completely unrelated plugins one-by-one and confirming that they each cause the error, e.g.:
  • .ignore
  • Eclipse Keymap
  • TestNG
• disable the plugins that were causing errors in the above step, and enable the same number of different plugins (so the total is 70 again) and observe that IntelliJ starts without error.

In other words, this bug is so weird that I really tried to confirm that I was seeing what I am seeing.

This has exactly the same symptoms as #3244, but I created a new bug as it seems to be triggered under opposite conditions, i.e. disabling the Android plugin for me would make the error more likely to appear since it might take my total enabled plugin count below 70.

Thanks for the report @stimut. We haven't seen this error lately, does it not happen when there are more plugins, but happens with less, to confirm? So if you install 70+ plugins, this somehow disappears?

[stimut]

Yes, that is correct @ivanporty. If I enable more than 70 plugins, from the marketplace or bundled doesn't matter, then the issue disappears. Disable some so there are fewer than 70 plugins enabled in total, the issue reappears.

[stimut]

I just updated IntellJ to 2024.3.2 and this (the 70 enabled plugin thing) is no longer true. I now have the same symptoms of #3244 where it's the Android plugin which seems to prevent GCA from working.

Closing as it's no longer relevant to me, but you can reopen of course if you want.
