Eclipse throwing error when copying and pasting

Question

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

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.
