I am using Eclipse 2019-03 (current version as of now) and JDK 12 on Windows 10. Whenever I run any code, it runs everything fine. However, it also shows a message colored red. This is the message I am getting:
JRE Oracle Corporation/12.0.1 is not supported, advanced source lookup disabled
Snapshot of the Eclipse console
Is there something I can do or should just ignore it? Thank you...
You should install the Java 12 plugin for eclipse.
Note that in eclipse 2019-06 and higher, that plugin isn't needed any more.
