NetBeans 11.0-vc4 Can't Set Source Code Level to 12
Hi All,
I'm currently using convenience binaries of NetBeans 11.0-vc4 on Windows 10 (64 bit system), running with OpenJDK-12 , etc.
I'm changing my projects source code level from 1.8 to 12 but unable to use new language features coming with new versions of Java, such as local variable type inference (aka var declarations).
I've observed these lines in my "IDE Log" repeating multiple times:
«
Even though the source level of C:\Users\pcUserName\Documents\NetBeansProjects\ProjectName\src\main\webapp;C:\Users\pcUserName\Documents\NetBeansProjects\ProjectName\src\main\resources is set to: 12, java.util.zip.CRC32C cannot be found on the system module path:
Changing source level to 1.8
»
I tried using Java 11 but it was the same: couldn't use Java 11 as it was degraded to 1.8.
I've searched on this mail list and on the internet but couldn't find anything solid; other than a mail thread Glenn Holmer started as I recall, which didn't end up with a solution.
What can/should I do so that I can use Java 12?

Close the IDE Log. Problem solved.

Bummer. You're right Gj, it worked. Thanks.
BTW, does the IDE Log telling degrading the source level from 11 to 1.8 have any significance? It's currently flooding my IDE Log view.

I'm assuming you're doing the above since 'var' is local variable type
inference, i.e., LOCAL.

Thanks Geertjan. I watched your YouTube video and retried but failed again. Now I'm trying on Linux with OpenJDK 11 but it's the same.
(1)CHECK: My `java -version` outputs:
«

(3)CHECK: Installed/updated nbjavac and oracle js parser plugins.
(4)CHECK: Created a new maven web project, added a class, added a field like:

My test field still doesn't pass valid. If I type "String" instead of "var" everything compiles successfully. Limited to Java 1.8.
When I open "View -> IDE Log" I see many occurrences of:
