I've created application using JFace viewer infrastructure including TextSelection.
While trying to run it, I've got the following error:

Added not full stacktrace by mistake. the last line is:

	at org.eclipse.jface.text.TextSelection.<clinit>(TextSelection.java:32)

Sorry, but I cannot reproduce the problem. Maybe you manually extracted stuff from the JAR and hence it fails with the security exception.

If you still see this problem then please provide steps (example) to reproduce it and reopen the bug.
