Multi Cursor Slow

I'm in a Java editor but it really happens in each editor. When I have round about 10 or 20 or ore multi carets and I change smth, it is really slow, it seems that the multi caret works synchronize? So line after line. It would be nice if it works in parallel, if this is working.

I added a screen capture that you can see how it is slow (Multi Cursor Slow) and will add the snapshot file for you.



P.S. I know that the file has errors because of the syntax errors, missed " but it doesn't matter.

Plugin debugjavac is slowing down whole implementation. Sending this to Mila, so he can evaluate this.
