Comment 1 Jerome Lanneluc CLA 2002-10-23 05:03:01 EDT 
Workaround is to delete the existing projects that need to be imported first, 
then import the external plugins.
Comment 2 Jerome Lanneluc CLA 2002-10-23 05:16:10 EDT 
SetClasspathOperation did not handle the case where a project is being deleted 
and another project's classpath is modified.

Fixed.
