I'm trying to provide my language built on xtext to the company to look at. I create an update site, install a clean eclipse (standard), point it at my update site, and install.
Everything installs fine, I create a new file, but when I try to edit it, after typing the first keyword I get:
An internal error occurred during: "XtextReconcilerJob".
java.lang.NullPointerException
at org.eclipse.xtext.util.EmfStructureComparator.internalIsSameStructure(EmfStructureComparator.java:50)
at org.eclipse.xtext.util.EmfStructureComparator.isSameStructure(EmfStructureComparator.java:45)

at org.eclipse.xtext.ui.editor.reconciler.XtextReconciler.run(XtextReconciler.java:291)
at org.eclipse.core.internal.jobs.Worker.run(Worker.java:53)
Googling around I found an exchange between a customer and company that was experiencing a similar issue and it turned out to be that org.eclipse.xtext.logging wasn't in the plugins directory, checking my plugins directory I don't have the JAR either, when I manually copy it in, no more crashes. If I install the xtext SDK and my plugin, no more crashes (which I guess is the work around).
How do I get my plugin to depend on org.eclipse.xtext.logging JAR so it's installed automatically? Or is there some deeper error I should be looking into my language for?
I'm using the latest "released" xtext so 2.4.3.v201309030823.

See this bugzilla : https://bugs.eclipse.org/bugs/show_bug.cgi?id=421741
The NPE has been solved four month ago and is avialable since version 2.5.0.
It happend only when you have enabled the DEBUG severity through some
log4j properties file. the plug-in org.eclipse.xtext.logging will set
the severity to WARN. not sure where that DEBUG severity comes from in
your environment.
