             Summary: NB-Javac
                 Key: NETBEANS-3655
                 URL: https://issues.apache.org/jira/browse/NETBEANS-3655
             Project: NetBeans
          Issue Type: Bug
    Affects Versions: 11.2
         Environment: Product Version: Apache NetBeans IDE 11.2
Java: 14-ea; OpenJDK 64-Bit Server VM 14-ea+29-1384
Runtime: OpenJDK Runtime Environment 14-ea+29-1384
System: Mac OS X version 10.15.2 running on x86_64; UTF-8; en_US (nb)

Using NB 11.2 on macos 10.15.2 and am using JEP 354: Switch Expressions so am compiling with JDK 14.
{noformat}
openjdk 14-ea 2020-03-17
OpenJDK Runtime Environment (build 14-ea+29-1384)
OpenJDK 64-Bit Server VM (build 14-ea+29-1384, mixed mode, sharing)
{noformat}
 
 Am also setting these additional compiler options in the NB project:
{noformat}
--enable-preview --source 14 -Xlint:unchecked -Xlint:preview
{noformat}
Installed nb-javac today to see if I could get "Compile on save" working.

With "Compile on save" disabled I need to manually build the project every time I want to test changes.

With "Compile on save" enabled I get this error when running the project.
