1. Open a Java file
2. Click on "Compare With ..." and choose the target (e.g. other branch).

=> Compare view is shown. The cursor position in the compare view is the one with the first difference.

Problem: The compare view should open at the same cursor position from which the comparison was started.

In particular with long Java files this is painful: You are only interested in the code at line 2987, but you have to scroll down the compare view to get to that position.

I think the current cursor position is a better default for the compare view than the first difference.

I set this bug from "enhancement" to "normal". I think this is actually a bug. 

In the past few days I had to adapt a large unit test file to a new API:

- I'm on some code line (say: line 2693)
- I choose "Compare With -> HEAD revision" 

=> The compare editor is opened at line 1.

I now need to

- go back to the source file
- remember the line number
- go back to the compare editor 
- jump to that line number in the compare editor

Not very convenient ...
