Michal Rama commented on NETBEANS-5491: --------------------------------------- I'm sorry, I didn't think of that. Anyway, I set the NetBeans runtime to JDK 16. Still, it can be run and everything seems OK. I can create a new project that also works. And the second existing project works, for which I only changed the version. So then I don't understand how he can't support it when everything (except my specific project) seems to work? > UnsupportedClassVersionError - If I set the NetBeans Runtime to Java 16, I > cannot run a project created in Java 15. > ------------------------------------------------------------------------------------------------------------------- > > Key: NETBEANS-5491 > URL: https://issues.apache.org/jira/browse/NETBEANS-5491 > Project: NetBeans > Issue Type: Bug > Components: java - Platform, java - Project, java - Source > Affects Versions: 12.3 > Environment: Windows 10, Apache NetBeans 12.3, Java 16 > Reporter: Michal Rama > Priority: Blocker > Labels: java, platform, project, runtime, version > Attachments: obr�zek02.png, obr�zek41.png > > > Hello, > I installed Java 16 and set it in the etc\netbeans.conf file > *netbeans_jdkhome="C:\Program Files\Java\jdk-16"* > However, upon startup, all projects reported an error.
