I have a big problem. Eclipse is hanging up when I do any copy/paste with Ctrl+C / Ctrl+V keys.
Is it due to the Eclipse validation code system?
Do I mess something in my Eclipse setting?
Here is my conf :
THE solution!! For me at least.
If CTRL + C works for some editor, not for other, then some plugin settings must have re-affected them to another command.
So you have to go to:
Window->Preferences->General->Startup and Shutdown
and try to disable, one by one the plugins activated on startup:
in my case, was "Dynamic Languages Toolkit Core UI"
I faced the problem when editing java code. Every time I typed CTRL + C the editor freezes for a short period of time.
In my case I only turned of the Go to declaration that is available in textual editors. SeeWindow -> Preferences -> General -> Editors -> Text Editors -> Hyperlinking.
In my case it seemed to be related to remote connection to the PC (working directly on the PC was not freezing it, while working remotely via Remmina it was). My fix was to unbind ALL commands on Ctrl+C (Window > Prefs > General > Keys), including the basic Copy (!!!). The operating system (or Eclipse core functionality) seems to handle clipboard keys correctly by default, no need to bind the additional "Copy" command to it. Now it's not freezing anymore, enjoy!
Just wanted to share my observations here as a pebble in the ocean, I had tried with all most all of the above options but it didn't solve my issues.
Actually, in my case the main culprit was the java file size, as lines of code increased encountering this hanging while copy & paste actions.
So quick workaround which I made to have a temp file for development and once all done, moving the code to respective java file, get me out of this hurdle. (I am a selenium + Java guy, so this workaround worked for me).
