"NullPointerException in Freemarker IDE"

--------------------------------------------------------------
I have a couple of files that consistently cause the Freemarker IDE in JBoss Tools to throw a NPE. All my other files are fine. The error occurs when I type a "${" prefix to a variable. The error message is:

Problems occurred when invoking code from plug-in: "org.eclipse.jface".

The stack trace is:
