I was installing a new JRE (JDK 1.4) when leaving the preferences
dialog I get an obscure error dialog "Update Class Path Failed: 49"
The obscure message looks like message format problem.

The workspace is a selfhosting workspace. Notice I had the same problem when
I converted a project to a PDE project.
