Eclipse CTRL + SPACE删除文本

Question

Somehow the CTRL + SPACE handling in Eclipse changed twice in the last weeks when existing text stands after positions in which we use it.

Let's say I want to create a BufferedReader for a file:

BufferedReader reader = new BufferedReader(something.filename);

Now I notice this doesn't work and I want to create a FileReader:

BufferedReader reader = new BufferedReader(new FileReader[CURSORPOSITION]something.filename);

However when I now hit CTRL + SPACE and choose the FileReader constructor from the list and hit ENTER , "something." (the part up to or including the space) gets deleted. Did this behaviour change recently and is it configurable? I remember being amazed that CTRL + SPACE handling somehow got better with a recent update but it seems it didn't last.

You have probably selected 'Completion overwrites' radio button on the Preferences>Java>Editor>Content Assist screen. 'Completion overwrites' overwrites whatever follows the cursor position. The other option is 'Completion inserts'.
