Geertjan Wielenga commented on NETBEANS-5491:
---------------------------------------------
When something isn't supported, i.e., JDK 16 in this case, then some things
work and some things don't. It's unpredictable. JDK 16 is not supported,
anything that works for you is great, and anything that doesn't is as expected.
> 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

> 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. NetBeans automatically
> set the *Java Platform* to *JDK 16* for them, but the *Source / Binary
> Format* was still *JDK 15*.
> !obr�zek41.png!
> !obr�zek02.png!
> So it was enough to change it to JDK 16, except for one project that still
> can't be run and I didn't figure out why.
> To run this project I need to close NetBeans and run it again in Java 15.
> Creating a new project in Java 16 would probably solve the problem, but why
> should I do it when there was no problem with all the other projects.
> Please help.
> Thank you
> PS.
