Eclipse is hanged on copy/paste in JavaScript files

Question

I\'ve been running Eclipse Helios 3.6 using the Java/CFEclipse IDEs, and finding some very strange and aggravating errors when trying to edit Javascript files. After the .js

Answer 1

First time met as Eclipse hangs on copy/cut for JavaScript files, and https://github.com/Nodeclipse/nodeclipse-1/issues/159

Current summary:

• size matters: big project can cause Eclipse JSDT to freeze (this is old issue as @andreialecu has collected https://github.com/Nodeclipse/nodeclipse-1/issues/159#issuecomment-68098716)
• hammer 100% solution is to remove JsNature for that one project
• more subtle is to disable only some JSDT features
  Window>Preferences>JavaScript>Editor>Mark Occurrences and maybe even Window->Preferences->General->Editors->Text Editors->Hyperlinking
• recommended by JSDT maintainers (for further observation): (by @vrubezhny )
  • get latest JSDT version
  • increase available memory settings
• use resource filters to hide more files in folders like build/dist/bower/vendor (by @ppartida )

And generally:

• pay attention what step you have taken when working with any software.
• experiment with little changes
