Eclipse Juno - Assertion Failed (Problems occurred when invoking code from plug-in: "org.eclipse.jface".)

I recently installed Eclispe Juno for Java for Android. I usually press . after a class name to know the associated methods, in case I wish to choose some other method instead of one already chosen from this list the following error pops up in the IDE.

How can tell IDE that this is not an error and there is no need to pop this message again and again?

enter image description here

The following is the error log from Eclipse

!ENTRY org.eclipse.jface 4 2 2012-07-01 02:04:29.242

Solution

  • Looks like the problem was caused by Coffee-Byte plugin of Eclipse (plugin used for folding) http://kosiara87.blogspot.in/2011/12/how-to-install-coffee-bytes-plugin-in.html?showComment=1341091754230#c8853438068212069468.
