Eclipse throwing error when copying and pasting

I am using Eclipse 3.5 SR2 for Java EE developers. Each time I press control+C or control+V for the first time after I open a file I get an error. After I close the error, I can successfully copy and paste. The error message made me believe that it was related to the Mylyn plugin, but I uninstalled it and still no difference. Has anyone else experience this problem? I also have the subclipse, adobe flex builder, and maven plugins installed.

The 'org.eclipse.mylyn.tasks.ui.hyperlinks.detectors.url' extension from plug-in 'org.eclipse.mylyn.tasks.ui' to the 'org.eclipse.ui.workbench.texteditor.hyperlinkDetectors' extension point failed to load the hyperlink detector.

Plug-in org.eclipse.mylyn.tasks.ui was unable to load class org.eclipse.mylyn.internal.tasks.ui.editors.TaskUrlHyperlinkDetector.

An error occurred while automatically activating bundle org.eclipse.mylyn.tasks.ui (520).

The 'org.eclipse.mylyn.java.hyperlink.detector.stack' extension from plug-in 'org.eclipse.mylyn.java.tasks' to the 'org.eclipse.ui.workbench.texteditor.hyperlinkDetectors' extension point failed to load the hyperlink detector.

Plug-in org.eclipse.mylyn.java.tasks was unable to load class org.eclipse.mylyn.internal.java.tasks.JavaStackTraceHyperlinkDetector.

This thread alludes to a similar error and mentions bug 214301 (which is solved in Egit 2.3.0, February 2013)

this looks like an inconsistent install of Mylyn causing this exception.
Could you check which versions of the Mylyn features you have installed (

Help >
About > Configuration Details

)?

Example of inconsistent Mylyn installation:

  • Mylyn 2.1 is installed
  • The Task List (mylyn-feature) and the structure bridges (ide-feature, pde-feature etc.) are updated to 2.2
  • The Focused UI (context-feature) remains at version 2.1

Solution:

update again and ensure that you get the "Mylyn Bridge: Eclipse SDK" feature

First, try running the update again via 

Help -> Software Updates -> Search
for new features

.. and ensure that all of the Mylyn features have been updated.

If you are using "Eclipse Helios", just update the Mylyn. It would fix the issue.

  1. Help -> Check for updates -> Select Mylyn entries -> Next -> Next and see the progress till it completes installation of new updates. Then

  2. Restart your eclipse.
