The plugin causes freezes in PhpStorm

[amakhrov]

Bug reports at PhpStorm issue tracker:

• https://youtrack.jetbrains.com/issue/WI-31233
• https://youtrack.jetbrains.com/issue/WI-31248
• https://youtrack.jetbrains.com/issue/WI-31204

The freezing issue was constantly reproduced until I disabled the plugin - after that it has gone.

@maxfilatov do you have any ideas on that?

[Jean85]

I can confirm this.

[Jean85]

Up! No news?
I should mention that I'm using PHPStorm 2016.1

[maxfilatov]

@Jean85 @amakhrov try to use latest builds please, problem should be fixed

[amakhrov]

@maxfilatov thanks! Right now works well, but since the issue appeared somewhat randomly, need more time for testing. Hopefully, it's resolved completely )

[Jean85]

Thanks! I will try it immediately, I'm using PHPStorm 2016.1.2; I will report back any problems.

[amakhrov]

@maxfilatov looks like the issue still happens in some cases.
Below is the data from idea.log.
Also here is the thread dump of the same event: threadDump-20160606-152450.txt

I can confirm that the freeze is still happening. I will disable the plugin for now.

[maxfilatov]

https://github.com/maxfilatov/phpuaca/releases/download/1.3.4-unstable-1/phpuaca-1.3.4-unstable-1.jar next try

[amakhrov]

@maxfilatov thanks! I've installed it, let's see if the issue occurs again.

[amakhrov]

@maxfilatov so far so good, no freezes since the last update. Still keeping an eye on it :)

[Jean85]

Great! Can you ping us when this version gets published?

[dbalabka]

@maxfilatov I have faced with following error in EAP version of PHPstorm with latest 1.3.4-unstable. Seems it's realated.

Not sure is it installed correclty because my PHPStorm always shows 1.3.4 version for some reason.
