I had worked on code for an hour or so, and then minimized it for several hours. Initially when I brought it up the UI didn't do anything at all, it eventually recovers and returns to normal responsiveness but this took about five minutes. I have observed this a couple of times now, attaching a thread dump this time.
Created attachment 14179 [details] Thread dump
Moving to tomcat since it looks like tomcat related issue. Looking at the thread dump I realize I do not understand one thing: how can there be tomcat threads mixed with IDE threads? I think I am missing something, I thought nothing from tomcat should be in IDE VM. Also, it seems there are 3 threads in CompyMaker.read which looks strange. Adding Petr and Martin to CC. Thanks for advice.
I'm not sure about this, too. It can be parser that we use internally, or httpserver? The copymakers ar for output/error stream handling.
Three copymakers is correct: input, output, error streams. The Tomcat thread is the internal HTTP server. I sometimes see this behavior too, and I think it could be because Windows swaps out the application, and then loads it back to the memory. Loading it back takes a long time. That's just a hypothesis, though.
Not a showstopper for 3.6.
This is a known problem on a Win platform. I am marking this as a dup of existing bug *** This issue has been marked as a duplicate of 40233 ***
