Created attachment 286017 [details]
Exported YourKit snapshot of some minutes of the freeze (the freeze is still on-going).

I have console output from a test that ran for over a day and a half, the output has millions of lines (the log from all the test runs). I intended to save the output to the file, but missclicked the Word Wrap button. Eclipse froze for about 20 minutes.

Stack trace from 4.15:

I'm guessing for millions of lines a long running operation cannot be avoided. If so, and the operation must be done in the UI thread, there should be a warning pop-up that Eclipse will be unusable during the long running operation.
