Eclipse hang when copying / pasting code

Question

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 vali

Answer 1

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"

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).
