org.eclipse.equinox.launcher.Main.run(Main.java:1450) at org.eclipse.equinox.launcher.Main.main(Main.java:1426) {code} In context of *.xhtml file, publicId is not defined, and is null. New Data Table wizard does not need a class template for class chooser input field 'Value Bean Class'. Either JavaAdapter.init should not call MetaClassTemplateHelper when publicId = null, or MetaClassTemplateHelper might do that check. Issue is related with changes to JBIDE-14476, which call methods on publicId in MetaClassTemplateHelper.getMetaTemplate().
