NullPointerException in XtextReconcilerJob when file extension has different capitalization [message #1671370]

Hi,

I have written a DSL with XText using a specific file extension, lets say ".bar". If I create a file with extension ".Bar" and edit it I will get a popup every couple of seconds saying: "An internal error occurred during: "XtextReconcilerJob". java.lang.NullPointerException"

I can solve it by adding two new entries in the plugin.xml for the "UI" plugin for my DSL, one for the "org.eclipse.xtext.extension_resourceServiceProvider" extension point and one for the "org.eclipse.emf.ecore.extension_parser" extension point, specifying the new file extension "Bar".

Is there a better way to do it to allow all capitalization of the DSL file extension? (Like "BAR", "bAr", "bAR", etc.)

Thanks, Fredrik

Hi,

what about filling out the corresponding variable (var fileExtensions = "mydsl,...,MYDSL") in the workflow, regenerate the language and merge the plugin.xml_gen to plugin.xml
