Working with JDK9 build. Attempt to create Unit test > Test for existing class does nothing. Following error is printed into terminal: [exec] WARNING [org.openide.loaders.TemplateWizard]: Wizard iterator of type org.netbeans.modules.junit.ui.wizards.SimpleTestCaseWizardIterator illegally returned null from the instantiate method
jdk9 build runs on Java 8 and project Java platform is JDK 9.
Not sure if this is indeed a jdk9 related issue. I am not sure what build you were seeing this issue on. The warning should not make any difference. Could it be related to bug 252759? Closing for now as there is no info. Please try using a latest build and if the issue is there reopen attaching the log.
