--- Comment #3 from Mat Booth mat.booth@redhat.com --- Hi,
Would it be possible to supply your workspace log from a session where you encountered this error?
And list which other Eclipse components you have installed:
rpm -qa | grep eclipse
And if you installed any third party plugins through "Help -> Install new software" or "Help -> Marketplace"
