Opening a large class gets stuck

Hello,

Could you please share logs folder zipped (https://intellij-support.jetbrains.com/hc/en-us/articles/207241085-Locating-IDE-log-files) to check recorded events and threaddumps?

Where is it and how should I share it？

You may find default location in mentioned article. You may use JetBrains Uploads Service: https://uploads.jetbrains.com

I have uploaded the log

Thanks! Is it reproducible with custom plugins disabled (Loaded custom plugins: arthas idea (2.37), File Expander (1.7), RestfulTool (1.4.5), Chinese (Simplified) Language Pack / 中文语言包 (222.202))? Do you use any antivirus software or data protection tools?

Tried today, no repetition, the last time the reason is that when I opened a big class, background tip is parsed, I don't have to wait for it to operate this class parsing is complete, then the whole idea is dead, if I wait it loaded in the operation, will not stuck, this is the last time I found

Sorry, what do you mean by "background tip is parsed"?

As shown in the picture，there is a progress bar that is being analyzed

刚才截图的时候，又卡机了。我已经关闭了所有的第三方插件，但是还是会崩溃。我打开的类是：rxjava-2.2.15.jar，io.reactivex.Observable

Just now, after several tests, it is necessary to wait for the analysis to be completed before normal use of IDEA, otherwise it will crash directly

Could you please clarify if IDE stuck or freeze? Could you please provide the whole logs folder zipped to check threadddumps/crashdumps?

I don't understand the difference between stuck and freeze，at this moment, IDEA is completely unavailable. The task manager must close the process and restart IDEA before it can be used。

In which directory I can provide threadddumps/crashdumps 

Sorry, I meant is it stuck or crash? If it crashes please check for crashdumps like "C:\Users\Administrator\\java_error_in_idea64_%p.log". You may upload the whole logs folder and crashdumps on JetBrains Uploads Service. 

No crashdumps logs were found

So, IDE doesn't crash, but freezes, right? Please share the whole logs folder for investigation. File opens fine on my side.

These are Freeze's logs？they were all generated on September 12th today. Shall I upload them to you?

I have uploaded the log

   Please try to disable "Settings | Editor | General | Appearence - Render documentation comments" option. Will it help?

Not much use, it seems

Do you have "Reader Mode"  enabled ("Settings | Editor | Reader Mode")? Please try to disable it.

I shut it down and it is normal now. Is that a bug?

We have similar issue on YouTrack: https://youtrack.jetbrains.com/issue/IDEA-266217/The-UI-freezes-when-I-read-the-JavaDoc-of-the-source-class-in-Reader-Mode

Okay, I hope you can optimize it. Thank you
